SrMn(II) 2Mn(III)(PO4)3.

ABSTRACT: The title compound, strontium trimanganese tris-(ortho-phosphate), was synthesized under hydro-thermal conditions. Its structure is isotypic to that of the lead analogue PbMn(II) 2Mn(III)(PO4)3. Two O atoms are in general positions, whereas all others atoms are in special positions. The Sr and one P atom exhibit mm2 symmetry, the Mn(II) atom 2/m symmetry, the Mn(III) atom and the other P atom .2. symmetry and two O atoms are located on mirror planes. The three-dimensional network of the crystal structure is made up of two types of chains running parallel to [010]. One chain is linear and is composed of alternating Mn(III)O6 octa-hedra and PO4 tetra-hedra sharing vertices; the other chain has a zigzag arrangement and is built up from two edge-sharing Mn(II)O6 octa-hedra connected to PO4 tet
