Bis(2-methoxybenzylammonium) diaquabis(dihydrogen diphosphato-κ2O,O′)manganate(II) dihydrate

Abstract

The asymmetric unit of the title compound, (C8H12NO)2[Mn(H2P2O7)2(H2O)2]·2H2O, consists of half an MnIIcomplex anion, a 2-methoxybenylammonium cation and a solvent water molecule. The MnIIcomplex anion lies across an inversion center, and has a slightly distorted octahedral coordination environment for the MnIIion, 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.
