Bis{[(η5)-cyclopentadienyl]tris(diethyl phosphito-κ3 P,P′,P′′)cobaltate(III)-κ3 O,O′,O′′]oxovanadium(IV)}-μ-oxalate

Abstract

The title compound {systematic name: bis[1,4(η5)-cyclopentadienyl]hexakis(μ-diethyl phosphito)-1:2κ6 P:O;3:4κ6 O:P-μ-oxalato-2:3κ4 O 1,O 2:O 1′,O 2′-dioxido-2κO,3κO-1,4-dicobalt(III)-2,3-divanadium(IV)}, [Co2V2(C5H5)2(C2O4)(C4H10O3P)6O2], is an oxalate-bridged dinuclear complex of oxovanadium(IV). The geometric center of the dimer lies on an inversion center. The unique Co atom is bonded to three P atoms and a cyclopentadienyl ring. The unique V atom has six O atom neighbors in an approximately octahedral arrangement; the V—O bond trans to the V=O bond is significantly lengthened.
