Abstract

In the title complex, (C8H14N2)[Co(H2P2O7)2(H2O)2]·2H2O, the CoII ion lies on an inversion center and is coordinated by two bidentate diphosphate ligands and two water molecules in a slightly distorted octahedral coordination geometry. The m-xylylenediaminium cation is located on a twofold rotation axis. In the crystal, a three-dimensional supramolecular assembly is constructed by O—H⋯O and N—H⋯O hydrogen bonds between the organic cations, complex anions and uncoordinated water molecules.

Highlights
