catena-Poly­[[bis­[triaqua[2,5-bis(4-pyridyl)-1,3,4-thia­diazo­le]cobalt(II)]]-μ4-tetravanadato].

The hydro­thermal reaction of cobalt acetate, vanadium pentoxide and 2,5-bis(4-pyridyl)-1,3,4-thia­diazo­le resulted in the title complex, [Co(V2O6)(C12H8N4S)(H2O)3], in which the cobalt(II) cation shows distorted octahedral geometry, coord­inated by one pyridine N atom, two O atoms from tetravanadate and three water mol­ecules.
