In the title compound, [V4O8(SeO3)2(C10H8N2)4], there are two distinct vanadium coordination environments. Alternating corner-shared VO4N2 octa­hedra and SeO3 pyramids result in eight-membered centrosymmetric V2Se2O4 rings. In addition, pairs of V centres form centrosymmetric V2O6N4 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.
