A Novel Hybrid Solid Constructed From Tetramolybdate And Copper Complexes With Mixed Ligands: [{(Cu Center Dot Phen)(2)(Tp)}{(Cu Center Dot Phen Center Dot H2o)(2)(Tp)}{Mo4o14}]

A novel copper molybdate with mixed ligands, [{(Cu center dot phen)2(tP)} {(Cu-phen center dot 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 P2(l)/c with a = 13.1711(7), b = 19.6132(10), c = 13.6910(7) angstrom,beta = 117.6870(10)degrees, V= 3131.8(3) angstrom(3), Z = 2, C64H44Cu4Mo4N8O24, M-r = 1946.99, D-c 2.065 g/cm(3), F(000) = 1920, mu(MoK alpha) = 2.198 mm(-1), R = 0.0810 and wR = 0.2012 for 4233 observed reflections (I > 2 sigma(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 bonding between adjacent layers further extends the compound into a 3-D framework.
