摘要

Dark red single crystals of SM2O2I were obtained from a reaction of SmI2 (in the presence of SmOI) and Na in a sealed tantalum ampoule at 650 degrees C. The title compound crystallizes in the monoclinic system (C2/m, Z = 4, a = 12.639(2), b = 4.100(1), c = 9.762(3) angstrom, beta = 117.97(2)degrees). The structure consists of corrugated [Sm2+Sm3+(O2-)(2)](+) layers of edge and vertex-connected SM4O tetrahedral units with I- anions separating the layers.
