摘要：

The preparation, structures and properties of the compounds MTh6Br15 (M = Mn, Fe, Co, Ni), Na(x)FeTh6Br15, Th6Br15H7 and Th6Br14C are described (MTh6Br15: Im3mBAR; M = Mn: a = 1150.85(3) pm; Fe: a = 1148.81(4) pm; Co: a = 1150.68(2) pm; Ni: a = 1151.43(4) pm; Th6Br15H7: a = 1140.7(1) pm; Th6Br14C: Cmca; a = 1576.4(3) pm, b = 1416.0(4) pm; c = 1312.4(3) pm). The structures of these compounds are closely related to those of the niobium halides Nb6F15 and Nb6Cl14, respectively. All compounds contain Th6Br12 clusters with octahedral Th6 cores and interstitial atoms in these cores. The magnetic properties of the compounds are discussed and compared with the results of Extended-Huckel calculations.
