X-ray powder diffraction study of the Cu2Cd1-xMnxSnSe4 alloys

The alloys of the Cu2CdSnSe4-Cu2MnSnSe4 system were investigated using the X-ray powder method that showed the continuous solubility of the original system components at 670 K. The refinement of the crystal structures of Cu2MnSnSe, (space group (SG) I42m, a = 0.57362(4) run, c = 1.14007(7) inn, c/a = 1.9875, R = 0.0531, R-P = 0.1186) and of the solid solution of Cu2Cd0.5Mn0.5SnSe4 composition (SG I42m, a = 0.57935(2) rim, c = 1. 14036(5) mn, c/a = 1.9683, R-P = 0.0455, R, = 0.0902) was performed. It was established that Cd mixes statistically with Mn in its crystallographic position.
