Bis{[(η(5))-cyclopentadienyl]tris(diethyl phosphito-κ(3) P,P′,P′′)cobaltate(III)-κ(3) O,O′,O′′]oxovanadium(IV)}-μ-oxalate

The title compound {systematic name: bis[1,4(η(5))-cyclo­penta­dien­yl]hexa­kis(μ-diethyl phosphito)-1:2κ(6) P:O;3:4κ(6) O:P-μ-ox­alato-2:3κ(4) O (1),O (2):O (1′),O (2′)-dioxido-2κO,3κO-1,4-dicobalt(III)-2,3-divanadium(IV)}, [Co(2)V(2)(C(5)H(5))(2)(C(2)O(4))(C(4)H(10)O(3)P)(6)O(2)], 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.
