Background:
- Strontium phosphates are of interest due to their diverse structural chemistry.
- Manganese phosphates exhibit various oxidation states and coordination environments.
Purpose of the Study:
- To synthesize strontium trimanganese tris-(ortho-phosphate).
- To elucidate the crystal structure of the title compound.
- To compare its structure with the lead analogue.
Main Methods:
- Hydro-thermal synthesis.
- Single-crystal X-ray diffraction analysis.
- Symmetry analysis of atomic positions.
Main Results:
- The crystal structure of strontium trimanganese tris-(ortho-phosphate) was determined.
- It is isotypic to PbMn(II)2Mn(III)(PO4)3.
- A 3D network of linked Mn(III)O6 octahedra/PO4 tetrahedra and Mn(II)O6 octahedra/PO4 tetrahedra chains forms channels hosting Sr(II) ions.
Conclusions:
- The synthesis and structural characterization of a novel strontium manganese phosphate were successful.
