Bis[tris(phenanthroline-κ2N,N′)cobalt(II)] undecatungsto(VI)vanado(V)phosphate dihydrate

Abstract

In the title hydrated salt, [Co(C12H8N2)3]2[PVW11O40]·2H2O, the complete Kegggin ion is generated by crystallographic inversion symmetry, which imposes statistical disorder on the O atoms of its central PO4 group. The V atom is statistically disordered over all the metal sites of the anion. In the cation, the Co2+ ion is coordinated by three bidentate 1,10-phenanthroline (phen) ligands, generating a distorted CoN6 octahedron. Possible very weak intramolecular C—H...π interactions occur in the cation. In the crystal, the components are linked by O—H...O and C—H...O interactions, building a three-dimensional network featuring one-dimensional voids along the c-axis direction.
