Synthesis and characterization of seven-coordinated polymeric mono[anti-<i>cis</i>-bis(2-hydroxy-1-naphthaldehyde) oxaloyldihydrazonato]monoaquobis-<i>cis</i>-dioxomolybdenum(VI)dihydrate complex

Abstract

The title compound synthesized from the reaction of MoO₂(acac)₂ with bis(2-hydroxy-1-naphthaldehyde)- oxaloyldihydrazone in ethanol-acetonitrile in 3:1 molar ratio under reflux is proposed to be a hexamer in which Iigands are arranged in sets of three in two parallel planes one above the other. The intraplanar metal atoms are bonded to each other by naphthoxo-bridges whereas the interplanar metal atoms are bonded to each other by Mo =O- - -Mo type of bridging. The anti-<i>cis</i>-configuration of the dihydrazone moieties leads to the chair conformation of the complex.
