The crystal structure of dicobalt(II) divanadium(V) disel-enium(IV) undeca-oxide, Co₂V₂Se₂O₁₁, exhibits a three-dimensional framework, the building units being distorted CoO₆ octa-hedra and VO₅ square pyramids arranged so as to form alternate chains along [010]. The framework has channels along [100] and [010] in which the two Ψ-SeO₃E (site symmetries m; E being the 4s² lone electron pair of Se(IV)) tetra-hedra reside and connect to the other building blocks. The structure contains corner- and edge-sharing CoO₆ octa-hedra, corner- and edge-sharing VO₅ square pyramids and edge-sharing Ψ-SeO₃E tetra-hedra. Co₂V₂Se₂O₁₁ is the first oxide containing all the cations Co(II), V(V) and Se(IV).
二钴（II）二钒（V）二硒（IV）十一氧化物Co₂V₂Se₂O₁₁的晶体结构呈现出三维框架，其构建单元是扭曲的CoO₆八面体和VO₅四方锥，它们排列成沿[010]方向的交替链。该框架在[100]和[010]方向上有通道，两个Ψ-SeO₃E（位点对称性为m；E为Se（IV）的4s²孤电子对）四面体位于其中，并与其他构建块相连。该结构包含角共享和边共享的CoO₆八面体、角共享和边共享的VO₅四方锥以及边共享的Ψ-SeO₃E四面体。Co₂V₂Se₂O₁₁是第一种包含所有阳离子Co（II）、V（V）和Se（IV）的氧化物。
