AbstractTwo coordination polymers (CPs), [Mn(bipmo)(pbtda)(H2O)]n (1), {[Cd(bipmo)(btda)]·2(H2O)]}n (2), (bipmo = bis(4-(1H-imidazol-1-yl)phenyl)methanone, H2pbtda = 2-phenylbutanedioic acid, H2btda = butanedioic acid), were synthesized by solvothermal methods. The products have been characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The topological structure of 1 is based on 2-nodal nets with the Schläfli symbol {63}{69·8}, while that of 2 features a system with a sixfold penetration with the Schläfli symbol {66}.

AbstractTwo coordination polymers, {[Co(bipmo)(tbip)]·3H2O}n (1) and {[Cd(bipmo)(tbip)]·3H2O}n (2) (bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone, H2tbip=5-tert-butylisophthalic acid), were synthesized by solvothermal methods and structurally characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. The results from single-crystal X-ray diffraction data indicate that the solid state structures of 1 and 2 consist of metal-aromatic carboxylate layers, which are pillared by weak interactions to generate a three-dimensional network. The topological structures of 1 and 2 are uninodal nets based on 3-connected nodes with the Schläfli symbol of {63}.

AbstractTwo Mn(II) complexes, {[Mn(BIPMO)2Cl2] · 2(H2O)}n (1) and {[Mn(BIPMO)2(SCN)2] · 2(CH3OH)}n (2) (BIPMO = bis(4-(1H-imidazol-1-yl)phenyl)methanone) with V-shaped BIPMO ligands, were synthesized and characterized by IR spectroscopy and elemental analyses along with their single-crystal X-ray diffraction analyses. The Mn(II) ions in 1 and 2 are both six-coordinated to four nitrogen atoms of four BIPMO ligands and two anions (Cl− for 1, and SCN− for 2) to form a distorted octahedral geometry.

AbstractA three-dimensional (3D) two-fold interpenetrated coordination polymer, {[Cd(bipmo)(bpda)]·1.25(H2O)}n (1), (bipmo = bis(4-(1H-imidazol-1-yl)phenyl)methanone, H2bpda = 1,1ʹ-biphenyl-2,2ʹ-dicarboxylic acid), was synthesized by a solvothermal method. It has been characterized by elemental analyses, infrared (IR) spectroscopy, and single-crystal X-ray diffraction. The topological structure of 1 consists of uninodal dia nets with two-fold penetration. The thermal stability and the luminescence properties of complex 1 were investigated.

New salts of 2-hydroxyaniline and 2-amino-3-hydroxypyridine with squaric acid were synthesized and characterized by elemental analyses, IR spectroscopy and thermal analyses (TG, DTG and DTA). The crystal structures of bis(2-hydroxyanilinium) squarate, [(C6H8NO+)2(C4O4)2−] (1) and bis(2- amino-3-hydroxy-pyridinium) squarate dihydrate, [(C5H7N2O+)2(C4O4)2−] · 2 H2O (2) were determined by single crystal X-ray diffraction. Both compounds crystallize in the monoclinic system, space group P21/c. The organic ammonium squarates decompose in two thermal steps

AbstractThe reaction of Cu(II) nitrate with sodium 2-chlorobenzoate (NaL1) and (E)-1,2-di(pyridin-4-yl)ethene (dpe) yields a new complex [Cu(L1)2(dpe)(H2O)] (1). When Zn(II) nitrate reacts with sodium 4-chlorobenzoate (NaL2) and 1,2-di(pyridin-4-yl)ethane (dpa), [Zn(L2)2(dpa)]·CH3OH (2) is obtained. Complexes 1 and 2 have been characterized by single-crystal X-ray diffraction, IR spectroscopy, and elemental and thermogravimetric analyses. 1 shows a 3D CdS network structure with uninodal 4-connected (65.8) topology; complex 2 displays a chain structure.

AbstractThe synthesis of two new copper(II) complexes with benzimidazole type ligands, Cu(tta)2(L1)2 (1) and Cu(tta)2(L1) (2) (where L1 is 3-(4-(1H-benzo[d]imidazol-1-yl)-4-methoxy phenyl)-1-phenylprop-2-en-1-one; tta is 2-thenoyltrifluoroacetonate), are reported. Their structures have been characterized by infrared spectroscopy, elemental analyses and single-crystal X-ray diffraction. The copper(II) ion of 1 is in a distorted octahedral environment, while that of 2 is in a distorted square-pyramidal environment. In both cases, the donor atoms are provided by oxygen atoms of the tta ligands and nitrogen atoms of the L1 ligands.

Two new isostructural complexes, namely, poly[aqua[μ3-2-(4-carboxyphenoxy)terephthalato-κ3 O 1:O 4:O 4′](1,10-phenanthroline-κ2 N,N′)cobalt(II)], [Co(C15H8O7)(C12H8N2)(H2O)] n or [Co(μ3-Hcpota)(phen)(H2O)] n , I, and poly[aqua[μ3-2-(4-carboxyphenoxy)terephthalato-κ3 O 1:O 4:O 4′](1,10-phenanthroline-κ2 N,N′)nickel(II)], [Ni(C15H8O7)(C12H8N2)(H2O)] n or [Ni(μ3-Hcpota)(phen)(H2O)] n , II, have been synthesized by solvothermal reactions. Complexes I and II were fully characterized by IR spectroscopy, elemental analyses, thermogravimetric analyses, and powder and single-crystal X-ray diffraction. They both present two-dimensional structures based on [M 2(μ-COO)2]2+ (M = CoII or NiII) dinuclear metal units with a fes topology and a vertex symbol (4·82). Interestingly, the positions of the two dimeric metal motifs and the two partially deprotonated Hcpota2− ligands reproduce regular flying butterfly arrangements flipped upside down and sharing wings in the ab plane. Magnetic studies indicate antiferromagnetic interactions (J = −5.21 cm−1 for I and −11.53 cm−1 for II) in the dimeric units, with Co...Co and Ni...Ni distances of 4.397 (1) and 4.358 (1) Å, respectively, that are related to double syn–anti carboxylate bridges.
