摘要:
                                A series of MoO2Cl2 complexes with acetoacetanilide derivatives were synthesized and studied by IR spectroscopy. The crystal and molecular structures of the MoO2Cl2 complex with acetoacet-2-toluidine (HL) were determined by X-ray diffraction analysis. The monoclinic crystals involved are a = 7.621(7) Angstrom, b = 9.498(3) Angstrom, c = 19.980(9) Angstrom, beta = 95.16(7)degrees, V = 1440(2) Angstrom (3), Z = 4, and space group P2(1)/n. The coordination polyhedron of the Mo atom is a distorted octahedron with two O oxoatoms in the cis-position relative to each other, two Cl atoms in the trans-positions, and two O atoms (HL) in the trans-positions to O(oxo).
