Synthesis, characterization, and crystal structures of two oxidomolybdenum(VI) complexes with hydrazones derived from 3-hydroxy-2-naphthoic hydrazide

摘要

Two mononuclear oxidomolybdenum(VI) complexes, [MoO_2(L ~1)(CH_3OH)]·CH_3OH (1) and [MoO_2(L ~2)(CH_3OH)] (2) (H_2L~1=3- hydroxynaphthalene-2-carboxylic acid (1-methyl-3-oxobutylidene) hydrazide,H _2L~2=3-hydroxynaphthalene-2-carboxylic acid [1-(5-chloro-2-hydroxyphenyl)methylidene]hydrazide), were synthesized and characterized by elemental analysis, IR spectra, and single crystal X-ray diffraction. The Mo atom in each of the complexes is six-coordinated by the NNO donor atoms of the hydrazone ligand, one methanol O atom, and two oxo O atoms, forming an octahedral geometry.
