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 Facial Serums distorted octahedral coordination environment for the MnII ion, formed by two bidentate dihydrogendiphosphate ligands and two water molecules.In the crystal, the components 30" Induction Range 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.
