摘要：

The crystal structure of Hg7Sb4Br6 (previously reported as HgSbBr) has been solved by the X-ray single crystal technique. Hg7Sb4Br6 crystallizes in the cubic system, space group Pa3, Z = 4, with cell dimensions a = 12.9940(9)Å. The structure consists of the three-dimensional positively charged [Hg6Sb4]4+ shell, and octahedral [HgBr6]4- anions. The antimony atoms in the shell are bound into Sb4-2 dumbells with short SbSb distance of 2.77 Å. The possible migration of Hg2+ ions along the fourfold axis is suggested. © 1992.
