Abstract
The reaction of [(Cp*Ta)2B4H9(μ-BH4)] (1; Cp* = η5-C5Me5) with [Fe2(CO)9] in hexane yielded [(Cp*Ta)2B5H7{Fe(CO)3}2] (2) and [(Cp*Ta)2B5H9{Fe(CO)3}4] (3) in moderate yield. Cluster 2 represents the first example of a bicapped pentagonal-bipyramidal metallaborane with a deformed equatorial plane, and 3 can be described as a fused cluster in which two pentagonal-bipyramidal units are fused through a common 3-vertex triangular face. Compounds 2 and 3 have been characterized by mass spectrometry and IR, 1H, 11B, and 13C NMR spectroscopy, and the geometric structures were unequivocally established by crystallographic analysis.
