Bis-[methyl-1-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S]nickel(II) 1 was prepared starting from methyl 2-hydroxycyclopent-1-encarbodithioate ligand (CPDT) and Ni(II), and catena-[(μ2-4,4′-Bipyril)-bis-(methyl-2-hydroxy-1-cyclopentene-2-dithiocarboxylate-O,S)]nickel(ΙΙ) 2 was prepared in good yields from 1 plus 4,4′-bipyridyl (bpy) by shish-kebab methodology. The structure of 1 was confirmed by FTIR, elemental analysis, 1H NMR, UV–vis in chloroform solution and in solid, XPS, and PXRD. Compound 2 was characterized by FTIR, elemental analysis, UV–vis in chloroform solution, and in solid, XPS, PXRD, ESR, and solid state magnetization measurements. The structure of the polymer was established mostly by PXRD, ESR, and magnetization.

Abstract The coordination polymer [Cu2(TDPH)4(QNX)].DMF, (QNX = Quinoxaline; TDPH = 3,3-thiodipropionic acid), has been prepared by reaction of copper acetate, TDPH, and quinoxaline. The compound was characterized by elemental analysis, FTIR spectroscopy, and single-crystal X-ray diffraction. The crystal is monoclinic with a P21/n space group and dimensions of a = 12.889(3) Å, b = 14.983(4) Å, c = 14.091(3) Å, α = 90 °, β = 90.200(11) °, γ = 90 °, V = 2721.18 (2) Å3, Z = 4. The ligands are hexagonally coordinated to the Cu(II) centre in the form of Cu2O4N with one nitrogen atom from the quinoxaline ligand, and four oxygen atoms from four TDPH molecules in a monodentate fashion. The Cu-Cu bond length was 2.642(1) and 2.629(1) Å for the Cu1----Cu1 and Cu2----Cu2 bonds. The QNX ligand bridged the two copper atoms. The catalytic reduction of 4-nitrophenol to 4-aminophenol using NaBH4 in the presence of [Cu2(TDPH)4(QNX)].DMF, as catalyst was completed within 11 minutes. The 4-aminophenol product was confirmed using 1H NMR spectroscopy.

A series of copper(ii) complexes of the ligand 2,6-bis(pyridin-3-ylethynyl)pyridine have been synthesised and characterised by 1H and DOSY NMR, IR and UV-Vis spectroscopies, mass spectrometry, elemental analysis and single crystal X-ray diffraction. In solution these systems display almost identical spectroscopic properties, however the solid state structures are shown to vary widely, depending upon the choice of anion. The tetrafluoroborate salt was revealed to be a discrete Cu2L4 cage-like helicate. The tosylate salt, whilst of the same Cu2L4 stoichiometry, was shown to be a coordination polymer. Finally the nitrate salt structure was observed to be a discrete Cu2L2 metallocycle.

As part of our synthetic efforts for new triplesalen derivatives, we reacted 2,4,6-triacetyl- 1,3,5-trihydroxybenzene (1) with excess Cu(ClO4)2 · 6H2O, imidazole, and ethylenediamine. However, not the triple ketimine derivative was formed but the mononuclear CuII complex [LCuII(ImH)]ClO4 · 0.5EtOH · 0.5H2O (HL = 6-(1-(2-aminoethylimino)ethyl)-2,4-diacetyl-1,3,5-trihydroxybenzene) with only one ketimine function. This complex forms a one-dimensional coordination polymer in the solid state through the apical binding of a keto-oxygen atom of one cation to the CuII ion of a neighboring cation. Magnetic measurements reveal the presence of weak antiferromagnetic intra-chain interactions

Dianionic N,N-chelating ligands play a crucial role in coordination chemistry, but reports on related complexes remain limited to certain types of ligands. In here, the reactions of two diprotic ligands, i.e., a biguanide and a carbothiamide, with trimethylaluminium, are reported, which give rise to mono- and dinuclear aluminium(III) complexes. In addition, single deprotonation of the diprotic biguanide using potassium bis(trimethylsilyl)amide gives rise to a one-dimensional coordination polymer. All complexes have been fully characterized, and their solid-state structures were determined by single crystal X-ray diffraction analysis.

AbstractA coordination polymer {[Mn(BDC-Cl4)(DMF)4](H2BDC-Cl4)}n (1) (H2BDC-Cl4 = 2,3,5,6-tetrachloro-1,4-benzenedicarboxylic acid) was synthesized by a resin-assisted solvothermal method and isolated by a flotation method in carbon tetrachloride. Complex 1 shows a one-dimensional wave-like coordination structure in the solid state. It is readily dissolved in water. The complex has been characterized using elemental analysis, IR spectroscopy, molecular conductivity, thermogravimetric analysis, and single-crystal and powder X-ray diffraction techniques.

1:2 complexes, CdX2(PPh3)2, where X = ClO4, NO3, CF3CO2 and 1:1 complex, Cd(CF3CO2)2PPh3, have been isolated and characterized by elemental analysis and by vibrational and 31P—{lH} nmr spectral measurements. Conductance measurements show that the complexes behave as non-ionic species in dichloromethane. The vibrational spectra of the perchlorato complex are consistent with a six-coordinate structure in the solid state as well as in solution but it is difficult to deduce the structures of the nitrato and trifluoroacetato complexes from the spectral data. Assignments for the metal–ligand stretching frequencies for all the four complexes have been proposed. The 3lP—{1H} nmr spectra of the four complexes have been discussed. Formation of the 1:3 and 1:4 complexes, Cd(ClO4)2(PPh3)3 and Cd(ClO4)2(PPh3)4, in solution, has also been established by 31P—{lH} nmr spectral measurements.

Multidentate N-heterocyclic compounds form a variety of metal complexes with many intriguing structures and interesting properties. The title coordination polymer,catena-poly[zinc(II)-bis{μ-2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole}-κ2N3:N3′;N3′:N3-zinc(II)-bis(μ-benzene-1,2-dicarboxylato)-κ2O1:O2;κ3O1,O1′:O2], [Zn2(C8H4O4)2(C11H10N4)2]n, has been synthesized by the reaction of Zn(NO3)2with 2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole (imb) and benzene-1,2-dicarboxylic acid (H2bdic) under hydrothermal conditions. There are two crystallographically distinct imb ligands [imb(A) and imb(B)] in the structure which adopt very similar coordination geometries. The imb(A) ligand bridges two symmetry-related Zn1 ions, yielding a binuclear [(Zn1)2{imb(A)}2] unit, and the imb(B) ligand bridges two symmetry-related Zn2 ions resulting in a binuclear [(Zn2)2{imb(B)}2] unit. The above-mentioned binuclear units are further connected alternately by pairs of bridging bdic2−ligands, forming an infinite one-dimensional chain. These one-dimensional chains are further connected through N—H...O hydrogen bonds, leading to a two-dimensional layered structure. In addition, the title polymer exhibits good fluorescence properties in the solid state at room temperature.
