The asymmetric unit of the title compound, (C8H12NO)2[Mn(H2P2O7)2(H2O)2]·2H2O, consists of half an Mn(II) complex anion, a 2-meth-oxy-benyl-ammonium cation and a solvent water mol-ecule. The Mn(II) complex anion lies across an inversion center, and has a slightly distorted octa-hedral coordination environment for the Mn(II) ion, formed by two bidentate dihydrogendiphosphate ligands and two water mol-ecules. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to (100). An intra-molecular N-H⋯O hydrogen bond is also observed.
标题化合物(C8H12NO)2[Mn(H2P2O7)2(H2O)2]·2H2O的不对称单元由半个Mn(II)络合阴离子、一个2-甲氧基苄基铵阳离子和一个溶剂水分子组成。Mn(II)络合阴离子位于一个对称中心上，Mn(II)离子具有略微扭曲的八面体配位环境，由两个双齿二氢磷酸根配体和两个水分子形成。在晶体中，各组分通过O-H⋯O和N-H⋯O氢键相连，形成平行于(100)的层。还观察到一个分子内N-H⋯O氢键。
