✦ Synopsis
In the title compound, (C 8 H 12 N) 2 [Co(H 2 P 2 O 7 ) 2 (H 2 O) 2 ], the Co atom is located on an inversion center and is surrounded by two dihydrogendiphosphate ligands and two water molecules in an octahedral coordination. The packing is organized in layers containing the cobaltate anions with organic cations arranged in the interlayer spaces and connected through hydrogen bonds to the anions.
