摘要：

Two modifications of Sm2Se3 could be obtained in form of single crystals by chemical transport reaction. We prepared starting from Sm2Se3 powders red brown crystals of Sm2Se3 in the defective Th3P4 type structure with the space group I $($) over bar$$ 43d and a = 878.2 pm as well as starting from SmSe1.9 and samarium metal black, prismatic crystals of Sm2Se3 in the U2S3 type structure with the space group Pnma and a = 1127.3 pm, b = 409.1 pm and c = 1103.2 pm.
