| Popis: | In contrast to most other structures of transition metal orthophosphates with composition M 3- xM’x(PO4)2·H2O, the three metallic sites in the structure of Mn2Zn(PO4)2·H2O show no statistical disorder. The title compound, Mn2Zn(PO4)2·H2O, was obtained under hydrothermal conditions. The structure is isotypic with other transition metal phosphates of the type M 3− 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. |
