摘要：

(Figure Presented) Unanticipated complexity: The first example of a 4,1,11-MC2B10 metallacarborane (see picture; Ru magenta, B pink, C gray, H white) is reported. Reduction and metalation of 1,12-Ph 2-1,12-closo-C2B10H10 at both room temperature and low temperature yields no fewer than five isomeric supraicosahedral metallacarborane products. Calculations identify two initial nido-[C2B10H12]2- species, each with one C atom that is not in the open face. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
