摘要：

The reaction of 1,2-dithiol-omicron-carborane, under basic conditions, with appropriate organic dihalogenated compounds results in the formation of macrocycles incorporating 7,8-dicarba-nido-undecaborate or 1,2-dicarba-closo-dodecaborane units. The synthesis of some non-cyclic dicarborane compounds containing only one sulfur per cage directly bonded to the cluster is described. On the basis of the different behaviour of the dithiolato compounds versus the monothiolato, a mechanism that explains the formation of partially degraded and non-degraded compounds is proposed. The molecular structure of tetramethylammonium 7,8-(3',6',9'-trioxaundecane-1',11'-dithiolato-SS')-dicarba-nido-undecaborate has been determined. It crystallizes in space group P2(1)/c with 4 formula units per cell. The cell dimensions are a = 14.058(7), b = 7.536(2), c = 22.980(9) angstrom, beta = 99.41-degrees.
