摘要：
New cadmium bromoantimonide Cd2SbBr2 is prepared by the standard tube method. Its crystal structure is solved by the direct methods and refined to R = 0.0328 for 1374 independent reflections and 69 variable parameters. The compound crystallizes in the monoclinic space group P2(1): a = 8.244(1), b = 9.920(1), c = 8.492(1) Angstrom, beta = 116.80(1)degrees. The presence of binuclear Sb-2(4-) anions (Sb-Sb = 2.78 Angstrom) with an octahedral environment comprised of six cadmium atoms is the most interesting feature of the structure. The Sb2Cd6 octahedra share equatorial vertices to form layers. The layer alternation motif is close to that reported for cadmium and mercury chloroarsenides.
