A novel copper molybdate with mixed ligands, [{(Cu·phen)2(tp)}{(Cu·phen·H2O)2(tp)}{Mo4O14}] (phen = 1,10-phenanthroline, tp = terephthalate) 1, has been hydrothermally synthesized and structurally characterized. The crystal belongs to monoclinic system, space group P21/c with a = 13.1711(7), b = 19.6132(10), c = 13.6910(7) , β = 117.6870(10)°, V = 3131.8(3) 3, Z = 2, C64H44Cu4Mo4N8O24, Mr = 1946.99, Dc = 2.065 g/cm3, F(000) = 1920, μ(MoKα) = 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 complex fragments and tp ligands bridging the clusters into a wave-like layer. The hydrogen bond- ing between adjacent layers further extends the compound 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.
