Abstract: A nickel coordination polymer with V-shaped ligands, {[(L1)2Ni(H2O)2] · 2(C8H5O4)}n, (L1 = 4-(1H-imidazol-1-yl)phenyl)methanone) has been synthesized under the solvothermal conditions. The structure has been determined by the single-crystal X-ray diffraction analysis and characterized by the infrared spectroscopy and elemental analysis. The crystal is crystallized in the monoclinic sp. gr. P21/c with the unit cell parameters a = 15.6387(3) Å, b = 8.0526(2) Å, c = 24.4791(6) Å, and β = 129.2350(10)°, Z = 2. The adjacent [Ni(H2O)2] units are linked by two bridging L1 ligands to form 1D looped chains, which are extended by the hydrogen bonds to yield a 3D framework. [ABSTRACT FROM AUTHOR]

A copper complex with V-shaped ligands, [( L )CuCl] ( 1), ( L1 = 4-(1 H-imidazol-1-yl)phenyl) methanone) has been synthesized and characterized by IR spectroscopy, elemental analyses and singlecrystal X-ray diffraction. The crystal of 1 is monoclinic, sp. gr. C2/ with the unit cell parameters a = 17.9496(13), b = 15.3440(13), c = 7.2983(7) Å, and β = 112.875(6)°, Z = 4, R = 0.0681, and wR = 0.1736 ( I > 2 σ). The solid state structure of 1 consists of 2D metal aromatic chloride layers, which are propagating along the bc plane to form a 3D network through hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title compound, CHCuFNOS ( 1), was synthesized by the reaction of Cu( tta) and L, ( L = ( E)-2-(4-(1 H-1,2,4-triazol-1-yl)benzylidene)-3,4-dihydronaphthalen-1(2 H)-one) in the dichloromethane solution. It crystallizes in the monoclinic, space group P2/ c with a = 33.8388(5), b = 9.3874(2), c = 21.8194(4) Å, β = 95.522(2), V = 6898.9(2) Å, Z = 8, D = 1.554 Mg/m, F(000) = 3272, µ = 0.834 mm, R = 0.0639, wR = 0.1637. The copper(II) ion of 1 is in a distorted square-pyramidal environment with four O atoms of the two tta ligands and one N atom of triazole ligand L. Single-crystal X-ray diffraction data revealed that the hydrogen bonds, weak C-H···π and π···π interactions in the crystals link the coordination units to form 3D supramolecular structures.
