摘要
Two new dioxomolybdenum(VI) complexes [MoO2(Bhbz) (CH3OH)] (1) and [MoO2(Cnbz)(CH3OH)] (2) with the benzohydrazone ligands H(2)Bhbz and H(2)Cnbz derived from 5-chlorosalicylaldehyde with 4-nitrobenzohydrazide and 3-bromosalicylaldehyde with 2-hydroxybenzohydrazide, respectively, have been synthesized and structurally characterized by physicochemical methods and single crystal X-ray determination. The crystal of (1) crystallizes in triclinic space group P-1, with a = 8.0014(9), b = 9.6294(10), c = 11.4204(12) angstrom, = 89.193(2), = 87.833(2), = 89.110(2)degrees, V = 879.11(16) angstrom(3), Z = 2, R-1 = 0.0464, wR(2) = 0.1185, S = 1.051. The crystal of (2) crystallizes in monoclinic space group P2(1)/c, with a = 7.4108(3), b = 18.7901(7), c = 12.6293(5) angstrom, = 104.4850(10)degrees, V = 1702.72(12) angstrom(3), Z = 4, R-1 = 0.0236, wR(2) = 0.0576, S = 1.061. X-ray analysis indicates that the structures of both complexes are similar to each other. The molybdenum atom in each complex is in an octahedral coordination environment, constructed by two oxo groups and NO2 donor set of the ligand, and one methanol O atom. The complexes have effective catalytic property for the oxidation of several olefins.
