Abstract Single crystals of Cu 2 SrGeS 4 and Cu 2 BaGeS 4 were prepared by using molten bromides as solvents. The compounds crystallize isotypically to their homologous thiostannates(IV) [1, 2]. (Cu 2 SrGeS 4 : Space group P3 2 , a = 614, 3 , b = 614, 3 and c = 1528, 2 pm; Cu 2 BaGeS 4 : Space group P3 1 , a = 621, 5 , b - 621, 5 and c = 1553, 4 pm). The atomic parameters and interatomic distances are reported.
