catena-Poly[[(2,2'-bipyridyl)oxidovanadium]-di-mu2-oxido-[(2,2'-bipyridyl)oxidovanadium]-mu3-selenito-bis[(2,2'-bipyridyl)dioxidovanadium]-mu3-selenito].
In the title compound, [V(4)O(8)(SeO(3))(2)(C(10)H(8)N(2))(4)], there are two distinct vanadium coordination environments. Alternating corner-shared VO(4)N(2) octahedra and SeO(3) pyramids result in eight-membered centrosymmetric V(2)Se(2)O(4) rings. In addition, pairs of V centres form centrosymmetric V(2)O(6)N(4) clusters via edge-sharing. These two kinds of secondary building units are linked in an ABABAB fashion to give an infinite chain whose nature is unprecedented in Se-V-O systems.
