Abstract: The title compound, [Co(C10H8N2)3]2[V4O12]·11H2O, is com­posed of two symmetry-related cations containing octa­hedrally coordinated CoII ions, a centrosymmetric [V4O12]4- anion with an eight-membered ring structure made up of four VO4 tetra­hedra, and 11 solvent water mol­ecules. The CoII cations and vanadate anions are isolated and build cation and anion layers, respectively. In addition, the title compound exhibits a three-dimensional network through intra- and inter­molecular hydrogen-bond inter­actions between water mol­ecules and O atoms of the anions, and the crystal structure is stabilized mainly by hydrogen bonds.

Formula: [Co(C10H8N2)3]2[V4O12]·11H2O
