A triclinic polymorph of catena-poly[[diaquacobalt(II)]--{-mellitato-²O¹:O⁴-bis[pentaaquacobalt(II)]}-⁴O²,O³:O⁵,O⁶] hexahydrate]

Abstract: A second, triclinic, polymorph of the title compound, {[Co₃(C₁₂O₁₂)(H₂O)₁₂]·6H₂O}_n, is reported. This polymorph forms a three-dimensional framework through O-HO hydrogen-bond interactions between the one-dimensional [Co₃{C₆(COO)₆}₃(H₂O)₁₂]_n chains and the solvent water molecules. The mellitate ligand lies on an inversion center.
