【 摘 要 】

Reaction of [MoO2(acac)2] (where acac = acetylacetonate) with two similar hydrazone ligands in methanol yielded two water coordinated mononuclear molybdenum(VI) oxo complexes with general formula [MoO2L(OH2)], where L = L1 = N'-(2-hydroxy-3-methoxybenzylidene)-2-methoxybenzohydrazide (H2L1), and L = L2 = N'-(3-ethoxy-2-hydroxybenzylidene)-2-methoxybenzohydrazide (H2L2). Crystal and molecular structures of the complexes were determined by single crystal X-ray diffraction method. All of the investigated compounds were further characterized by elemental analysis and FT-IR spectra. Single crystal X-ray structural studies indicate that the hydrazone ligands coordinate to the MoO2 cores through enolate oxygen, phenolate oxygen and azomethine nitrogen. The Mo atoms in both complexes are in octahedral coordination.
