Molybdenum(Iv) halide complexes with the chelating ligands Schiff bases, acetylacetoae, and 8-hydroxyquinoline

Abstract

A range of molybdenum(1V) complexes of the type Mo(che1ate)₂X₂ have been prepared where (chelate) = N-substituted salicylaldimine, acetylacetone, and 8-hydroxyquinoline; X = halogen. They can be prepared by direct substitution of chlorine from MoCl₄(MeCN)₂ by a chelating group or by oxidative substitution of MoX₃py₃. The magnetic and spectroscopic properties of these six-coordinate d2 complexes are discussed.
