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.
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.
