A novel copper molybdate with mixed ligands, [{（Cu·phen）e（tp）} {（Cu·phen·H2O）2（tp）} {Mo4O14}（phen = 1,10-phcnanthroline, tp = tercphthalate） 1, has been hydrothermally synthesized and structurally characterized. The crystal belongs to monoclinic system, space group P2l/c with a = 13.1711（7）, b = 19.6132（10）, c= 13.6910（7） A, β = 117.6870（10）°, V= 3131.8（3） A^3, Z= 2, C64H44Cu4MoaN8O24, Mr= 1946.99, D, = 2.065 g/cm^3, F（000） = 1920,μ（MoKa） = 2.198 mm ^1, R = 0.0810 and wR = 0.2012 for 4233 observed reflections （I 〉 2σ（I））. The structural analysis indicates that the title compound contains a discrete tetramolybdate cluster decorated with copper colnplcx fragments and tp ligands bridging the clusters into a wave-like layer. The hydrogen bonding between adjacent layers further extends the COlnpound into a 3-D framework.
The reactions of Co（C1O4）2·6H2O and Co（NO3）2.6H2O with the di-Schiff base ligand N,N＇-bis-（1-benzimidazo-2-yl-ethylidene）-ethane-1,2-diamine （LA） in ethanol have been investigated. The reactions of LA with excess amount of cobalt salts yield the six-coordinate complexes [CoL2]（ClO4）E·H2O 1 and [CoL2]（NO3）E·H2O 2 as isolatable products （L= N-（1- benzimidazo-2-yl-ethylidene）-ethane-1,2-diamine）, where L is a tri-dentate mono-Schiff base ligand, resulting from the hydrolysis of the precursor di-Schiff base LA. Both complexes were characterized by X-ray crystallography. Crystal data for complex 1： monoclinic, space group P21/c, a = 11.9214（10）, b = 23.5828（17）, c = 14.0387（12）A, β = 135.219（4）°, C22H30Cl2CoN8O9, Mr = 680.37, V = 2780.1（4） A^3 ,Z = 4, Dc = 1.625 g/cm^3,μ（MoKa） = 0.876 mm^-1, F（000） = 1404, the final R = 0.0725 and wR = 0.1530 for 5726 observed reflections （I 〉 2σ（I））. Crystal data for complex 2： monoclinic, space group P21/c, a = 18.2162（16）, b = 10.0610（6）, c = 18.593（2）A, β = 130.099（3）°, C22H30CoN10O7, Mr = 605.49, V = 2606.5（4） A3 Z = 4, Dc = 1.543 g/cm^3,μ（MoKa） = 0.722 mm^-1, F（000） = 1260, the final R = 0.0619 and wR = 0.1429 for 5194 observed reflections （I 〉 2σ（I））. X-ray diffraction analysis reveals that each cobalt atom in the two complexes is chelated by six nitrogen atoms from two tridentate iigands L, exhibiting a slightly distorted octahedral coordination sphere. In both complexes, the strong hydrogen-bonding interactions between the lattice waters and N-H groups of the ligands result in 1D chains which are further connected by ClO4^- （or NO3^-） groups to form a 3D framework. In complex 2, the strong π-π interactions increase the stability of the structure.

A new compound, (H3O)3{Na3(H2O)13(Cu(Gly)2)2(H2W12O42)}·11H2O (1), has been synthesized and structurally characterized, which represents the first example of a polyoxotungstate-surface being decorated with amino acid ligand. Two cis-{Cu(Gly)2}2+ engraft into the (H2W12O42)10- with Cu-O bond of 0.241 2(7) nm, and Na+ ions linked these (Cu(Gly)2)2(H2W12O42)6- clusters into a one-dimensional chain. CCDC: 278000.
