Oxotris­(quinolin-8-olato-κ²O,N)­tantalum(V) di­chloro­methane disolvate

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].
