Abstract: The asymmetric unit of the title compound, (C8H12NO)2[Mn(H2P2O7)2(H2O)2]·2H2O, consists of half an MnII complex anion, a 2-meth­oxy­benyl­ammonium cation and a solvent water mol­ecule. The MnII complex anion lies across an inversion center, and has a slightly distorted octa­hedral coordination environment for the MnII ion, formed by two bidentate dihydrogendiphosphate ligands and two water mol­ecules. In the crystal, the components are linked by O-H...O and N-H...O hydrogen bonds, forming layers parallel to (100). An intra­molecular N-H...O hydrogen bond is also observed.
