The alloys of the Cu 2 CdSnSe 4 –Cu 2 MnSnSe 4 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 Cu 2 MnSnSe 4 (space group (SG) I&4macr;2m, a = 0.57362(4) nm, c = 1.14007(7) nm, c / a = 1.9875, R I = 0.0531, R P = 0.1186) and of the solid solution of Cu 2 Cd 0.5 Mn 0.5 SnSe 4 composition (SG I&4macr;2m, a = 0.57935(2) nm, c = 1.14036(5) nm, c / a = 1.9683, R I = 0.0455, R P = 0.0902) was performed. It was established that Cd mixes statistically with Mn in its crystallographic position. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
