Synthesis and study of the phosphate Cs2Mn0.5Zr1.5(PO4)3
The new phosphate Cs 2 Mn 0.5 Zr 1.5 (PO 4 ) 3 was synthesized for the first time and characterized by X-ray diffraction. Its crystal structure was refined in space group P 2 1 3, Z = 4 at 25°C ( a = 10.3163(1) Å, V = 1097.93(1) Å 3 ), by the Rietveld method using the powder X-ray diffraction data....
