A Novel Aggregation of (4-Nitrophenoxy)acetic Acid [1-(2-Hydroxyphenyl)methylidene]hydrazide and Its Dioxomolybdenum(VI) Complex: Synthesis and Structure

Abstract

A novel aggregation of (4-nitrophenoxy)acetic acid [1-(2-hydroxyphenyl)methylidene]hydrazide and its dioxomolybdenum(VI) complex has been prepared by the reaction of salicylaldehyde, (4-nitrophenoxy)acetic acid hydrazide, and MoO₂(acac)₂ in methanol. The compound was characterized by elemental analysis and single-crystal X-ray diffraction method. The asymmetric unit of the compound contains a free hydrazone molecule and a dioxomolybdenum(VI) complex molecule. The Mo atom in the complex molecule is coordinated by one phenolate O, one imino N, and one enolic O atoms of the hydrazone ligand, two oxo O atoms, and one water O atom, forming an octahedral coordination.
