【 摘 要 】

The title compound, Mn2Zn(PO4)2·H2O, was obtained under hydro­thermal conditions. The structure is isotypic with other transition metal phosphates of the type M3−xM′x(PO4)2·H2O, but shows no statistical disorder of the three metallic sites. The principal building units are distorted [MnO6] and [MnO5(H2O)] octa­hedra, a distorted [ZnO5] square pyramid and two regular PO4 tetra­hedra. The connection of the polyhedra leads to a framework structure. Two types of layers parallel to (-101) can be distinguished in this framework. One layer contains [Zn2O8] dimers linked to PO4 tetra­hedra via common edges. The other layer is more corrugated and contains [Mn2O8(H2O)2] dimers and [MnO6] octa­hedra linked together by common edges. The PO4 tetra­hedra link the two types of layers into a framework structure with channels parallel to [101]. The H atoms of the water mol­ecules point into the channels and form O—H⋯O hydrogen bonds (one of which is bifurcated) with framework O atoms across the channels.
