摘要：

The structure of 1-phenyl-2-trimethylsilyl-1,2-dicarba-closo-dodecaborane(12), C11H24B10Si, has been determined crystallographically. The C-cage-C-cage distance is 1.708 (4) Angstrom, only slightly longer than in the 2-methyl analogue. However, in contrast to the 2-methyl and 2-bromo analogues, relief from steric congestion is afforded by a mutual 'bend back' of both the phenyl and trimethylsilyl groups, the latter involving deformation of valency angles both at Si and the C-cage atom to which it is attached.
