The title compound {systematic name: bis[1,4(η(5))-cyclo-penta-dien-yl]hexa-kis(μ-diethyl phosphito)-1:2κ(6)P:O;3:4κ(6)O:P-μ-ox-alato-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 cyclo-penta-dienyl ring. The unique V atom has six O atom neighbors in an approximately octa-hedral arrangement; the V-O bond trans to the V=O bond is significantly lengthened.
标题化合物{系统名称：双[1,4(η⁵)-环戊二烯基]六(μ-二乙基亚磷酸酯)-1:2κ⁶P:O;3:4κ⁶O:P-μ-草酸根-2:3κ⁴O(1),O(2):O(1'),O(2')-二氧化物-2κO,3κO-1,4-二钴(III)-2,3-二钒(IV)}，[Co₂V₂(C₅H₅)₂(C₂O₄)(C₄H₁₀O₃P)₆O₂]，是草酸根桥连的氧钒(IV)双核配合物。二聚体的几何中心位于对称中心上。独特的Co原子与三个P原子和一个环戊二烯基环键合。独特的V原子有六个O原子邻位，呈近似八面体排列；与V=O键反式的V-O键明显变长。
