M. M. Amini, T. Tamizkar, M. Mirzaee and S. W. Ng

Abstract: The Ta^V atom in the title compound, [Ta(C₉H₆NO)₃O]·2CH₂Cl₂, is chelated by three quinolin-8-olate ligands and exists in a pentagonal-bipramidal geometry. The Ta and oxo O atoms and one of the quinolin-8-olate ligands lie on a mirror plane that relates the other two quinolin-8-olate ligands to one another. The compound is isostructural with the Nb^V dichloromethane disolvate reported by Amini, Mirzaee, Yeganeh & Ng [Acta Cryst. (2004), E60, m147-m148].
