 Title    Röntgenographische Strukturuntersuchung von Cäsiumhexaoxo-tetrahydroxo-pentaborat-2-dimethylsulfoxid X-ray Study of the Structure of Cesiumhexaoxo-tetrahydroxo-pentaborate-2-dimethyl Sulfoxide  
 Abstract    The compound Cs[Bs0 6 (OH)4 ] • 2 DMSO was prepared by hydrolysis of tris(methoxy)-borane in organic solvents with small amounts of water in presence of cesium ierf-butylate and recrystallized in DMSO (dimethyl sulfoxide). Cs[Bs0 6 (0 H)4 ] • 2 DMSO crystallizes in the monoclinic space group P2i/a with a = 9.593(2), 6 = 19.179(4), c = 11.585(2) Ä, ß = 119.99(2)° and Z — 4. The crystal structure was determined by single-crystal diffracto­ meter data and refined to a conventional R value of 9.9%. The crystal structure consists of chains of pentaborate anions [Bs0 6 (OH)4 ]-linked by hydrogen bonds. The cesium cation and the DMSO molecules join the chains to sheets by coordination and hydrogen bonds respectively.
