Two new related coordination polymers, namely, [Pb(L)(1,4-ndc)] · 0.5H2O (1) and [Cd(L)(1,4- ndc)] · 0.5H2O (2), where L = 2-(3-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,4- ndc = 1,4-naphthalenedicarboxylate, were synthesized under hydrothermal conditions. Crystal data for 1: C62H36F2N8O9Pb2, monoclinic space group C2/c, a = 15.874(3), b = 19.982(4), c = 16.045(3) Å, β = 94.26(3), V = 5075.3(18) Å3, Z = 4. Crystal data for 2: C62H36Cd2F2N8O9, monoclinic space group P21/n, a = 12.622(2), b = 14.038(3), c = 14.938(3) Å , β = 100.81(2), V = 2600.0(8) Å3, Z = 2. In compound 1, the 1,4-ndc ligands connect the Pb(II) atoms to yield a chain structure. The L ligands are attached on the same side of the chain. The π-π interactions between L ligands of neighboring chains result in a 2D supramolecular architecture of 1. In compound 2, 1,4-ndc ligands link the Cd(II) atoms to generate a layer structure. The L ligands from adjacent layers are paired to furnish strong π-π interactions. Further, these layers are extended into 3D supramolecular architectures through these π-π interactions. The structural differences of 1 and 2 suggest the importance of the metal centers in the construction of the coordination polymers. The luminescent properties of the compounds were also investigated.

Two new coordination polymers, [Pb(L)(1,3-bdc)] ·2.5H2O (1) and [Cu(L)(1,4-bdc)] (2) (L = 2- (4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline; 1,3-bdc, 1,4-bdc = 1,3- and 1,4-benzenedicarboxylate), have been hydrothermally synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. Crystal data for 1: C54H40F2N8O13Pb2, triclinic, space group P¯1, a = 9.3468(19), b = 9.4607(14), c = 15.581(3) Å , α = 90.44(4), β = 101.13(3), γ = 113.97(3)°, V = 1229.6(4) Å3, Z = 1.

Compound 2 shows a layer structure, with stacking by π-π interactions to give a three-dimensional (3D) supramolecular architecture. N-H· · ·O hydrogen bonding further stabilizes the structure of 2.

Two new coordination polymers constructed with the 1,10-phenanthroline derivative 2-(2-chloro- 6-fluorophenyl)-1H-imidazo[4,5-f][1,10]-phenanthroline (L) and different carboxylates, namely, [Cd2(L)2(1,3,5-BTC)(Cl)]·H2O (1) and [Co2(L)2(1,2,4,5-BTC)(H2O)2] (2), have been synthesized under hydrothermal conditions (1,3,5-BTC = 1,3,5-benzenetricarboxylate anion and 1,2,4,5-BTC = 1,2,4,5-benzenetetracarboxylate anion). Crystal data for 1: C47H25Cd2Cl3F2N8O7, triclinic, space group P¯1, a = 10:1084(5), b = 14:9285(7), c = 15:2930(4)Å , α = 72:1050(10), β = 86:160(2), γ = 79:6000(10)°, V = 2159:88(16) °A3, Z = 2.

Their crystal structures have been determined by singlecrystal X-ray diffraction analyses, and the compounds further characterized by physico-chemical and spectroscopic methods. In 1, each 1,3,5-BTC anion connects five Cd(II) atoms to form a double chain. These chains are extended into 2D supramolecular networks through μ - μ interactions. N-H...Cl, N - H...O and O - H...N hydrogen bonding interactions further stabilize the network of 1. In 2, each 1,2,4,5-BTC anion bridges four Co(II) atoms to yield a chain. μ-μ interactions among adjacent chains result in a 2D supramolecular architecture.

Two ZnII-based coordination polymers (CPs) were synthesized by the hydrothermal method, using Zn(NO3)2·6H2O and furan-2,5-dicarboxylic acid (FDCA) in dimethylformamide (DMF) solvent, at 95 °C. Poly[tetrakis(dimethylazanium) [tetrakis(μ2-furan-2,5-dicarboxylato-κ2 O 2:O 5)dizinc(II)]], {(C2H8N)4[Zn2(C6H2O5)4]} n or {[DMA]4[ZnII 2(FDC)4]} n (DMA = dimethylazanium and FDC = furan-2,5-dicarboxylate), (1), was obtained with a 1:1 molar ratio of ZnII and FDCA. It crystallized in the monoclinic space group C2/c. Coordinated by ZnII ions, FDC2− ligands form 21 double-stranded helices propagating along the b axis. The helices are interconnected and extend laterally in the a direction, forming a two-dimensional (2D) sheet-like network. The 2D sheets are stacked along the c direction without interconnections. DMA cations are cocrystallized in (1) and are hydrogen bonded with carboxylate O atoms of the FDC2− ligands. The hydrogen-bonding pattern consists of R 2 2(4) and R 2 2(10) motifs alternating in a chain. Poly[bis(dimethylazanium) [bis(μ4-furan-2,5-dicarboxylato-κO 2:κO 2′:κO 5:κO 5)bis(μ3-furan-2,5-dicarboxylato-κO 2:κO 2′:κO 5)dizinc(II)] dimethylformamide 3.08-solvate], {(C2H8N)2[Zn2(C6H2O5)4]·3.08C3H7NO} n or {[DMA]2[ZnII 3(FDC)4]·3.08DMF} n , (2), was obtained with a 1:2 molar ratio of ZnII and FDCA. It crystallized in the monoclinic space group P21/c, forming a three-dimensional network. The pores are filled with DMA cations and DMF solvent molecules.

Abstract Ph2Sn(O2PMe2)2 has been synthesized by the reaction of HO2PMe2 with Ph2SnO in toluene or by treating HO2PMe2 with Ph2SnCl2 in methanol. X-ray diffraction studies of Et2Sn(O2PMe2)2 and Ph2Sn(O2PMe2)2 show that the O2PMe2 ligands function as bidentate bridges between the tin atoms. The ethyl and the phenyl groups are in trans-position in the resulting octahedral environment around tin. Et2Sn(O2PMe2)2 crystallizes in the monoclinic space group P21/n (a = 817.11(9), b = 974.1(1), c = 970.1(1) pm, β = 113.749(6)°, Z = 2 and R = 0.032) and con­sists of a polymeric layer structure with centrosymmetric (SnOPO)4 sixteen-membered rings. Ph2Sn(O2PMe2)2 also crystallizes monoclinically in the space group P21/n (a= 1060.9(1), b = 999.4 (1), c = 1768.9(2) pm, β = 90.93(1)°, Z = 4 and R = 0.057) and has a polymeric ring-chain structure with centrosymmetric (SnOPO)2 eight-membered rings. The IR and Raman spectra of Ph2Sn(O2PMe2)2 have been assigned and discussed in the light of structural information. The Sn(O2PMe2)+ ion represents the base peak in the mass spectrum of Ph2Sn(O2Me2)2.

Coordination polymers (CPs) have attracted increasing interest in recent years. In this work, two new CPs, namely poly[[aquabis(2,2′-bipyridine-κ2 N,N′){μ3-5-[(4-carboxylatophenoxy)methyl]benzene-1,3-dicarboxylato-κ4 O 1,O 1′:O 3:O 5}(μ-formato-κ3 O:O,O′)dicadmium(II)] monohydrate], {[Cd2(C16H9O7)(HCO2)(C10H8N2)2(H2O)]·H2O} n (1), and poly[[(2,2′-bipyridine-κ2 N,N′){μ3-5-[(4-carboxylphenoxy)methyl]benzene-1,3-dicarboxylato-κ4 O 1,O 1′:O 3:O 5}manganese(II)] sesquihydrate], {[Mn(C16H10O7)(C10H8N2)]·1.5H2O} n (2), have been prepared using the tricarboxylic acid 5-[(4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylic acid and 2,2′-bipyridine under hydrothermal conditions. CP 1 displays a two-dimensional layer structure which is further extended into a three-dimensional (3D) supramolecular structure via intermolecular π–π interactions, while CP 2 shows a different 3D supramolecular structure extended from one-dimensional ladder chains by intermolecular π–π interactions. In addition, the solid-state luminescence spectra of 1 and 2 were studied at room temperature.

Copper(II) and zinc(II) bis(4,4,4-trifluoro-1-phenylbutane-1,3-dionato) compounds with pyrimidin-2-amine (pyr2a), pyrazine (pyz) and 1,2-bis(4-pyridyl)ethane (dpet) were prepared and solid-state structures of coordination polymers [M(tfpb)2(pyr2a)]∞[M= Cu (1), Zn (2); tfpb = 4,4,4-trifluoro-1-phenylbutane-1,3-dionate], [M(tfpb)2(pyz)]∞[M= Cu (3), Zn (4a, 4b)] and [Cu(tfpb)2(dpet)]∞(5), respectively, were determined by single-crystal X-ray analysis. The coordination of metal centers in all compounds is octahedral with nitrogen ligands occupying the axial positions. Compound (1) crystallizes in the triclinic space group P\bar 1, whereas (2) crystallizes in the monoclinic space groupP2/n. Differences are due to the different orientation of adjacentM(tfpb)2units, whereas the orientation of pyrimidin-2-amine is the same in both compounds. Polymeric chains in (1) and (2) contain intramolecular N—H...O hydrogen bonding between amino and carbonyl groups. Room-temperature structures (3) and (4a) are isomorphous adopting the monoclinic space groupC2/m; however, on cooling crystals (4a) to 150 K a single-crystal-to-single-crystal transformation to (4b) possessing the triclinic space group P\bar 1 was observed. Compound (5) crystallizes in the triclinic space group P\bar 1 and contains a parallel aggregation of chains in contrast to the known structure of the non-fluorinated benzoylacetonato ligand, where chains aggregate in a perpendicular fashion. In the compounds studied intramolecular C—H...O and/or C—H...F interactions are present. The neighboring chains are linked by π...π interactions and in some compounds also by C—H...π interactions [(1), (4b), (5)].

Four new metal diphosphonates Zn ( pyHhedpH )⋅ H 2 O (1), Cd ( pyHhedpH )⋅ H 2 O (2), Pb ( pyHhedpH )⋅ H 2 O (3) and Pb 2( pyHedpH )2(4) (pyHhedpH3 = 2-(4-pyridyl)-1-hydroxyl-1,1-ethylidenediphosphonic acid, pyedpH4 = (2-(pyridin-4-yl)ethene-1,1-diyl)diphosphonic acid) were synthesized under hydrothermal conditions. Compounds 1 and 2 are isostructural and have ladder-like chain structures in which the {M2((μ - O )2)}(M = Zn , Cd ) dimer units are connected by O - P - O bridges. Compound 3 shows a unique type of double chain structure, in which the adjacent { Pb 2(μ - O )2} dimers are bridged by O - P - O and O - P - C - O groups into a chain. Compound 4 has a 2D structure, where the vertex-shared { PbO 5} polyhedra are connected by { CPO 3} tetrahedra through corner-sharing. The photoluminescence properties of compounds 1-4 were studied. Their potential as soft-oxometalate precursors is also discussed.
