摘要

We report the synthesis, isolation and structural characterization of several moderately air stable nidometallaboranes that represent boron rich open cage systems. The reaction of [Cp*CoCl](2), (Cp* = eta(5)-C5Me5), with [BH3 center dot thf] in toluene at ice cold temperature, followed by thermolysis in boiling toluene produced [(Cp*Co)B9H13], 1 [(Cp*Co)(2)B8H12], 2 and [(Cp*Co)(2)B6H10] 3. Building upon our earlier reactivity studies on rhodaboranes, we continue to explore the reactivity of dicobalt analogues of octaborane(12) cluster 3 with [Fe-2(CO)(9)] and [Ru-3(CO)(12)] at ambient conditions that yielded novel fused clusters [Fe-2(CO)(6)(Cp*Co)(2)B6H10], 4 and [Ru-4(CO)(11)(Cp*Co)(2)B3H3], 5 respectively. In an attempt to synthesize a heterometallic metallaborane compound we performed the reaction of [(Cp*Rh)(2)B6H10], 6 with [Cp*IrH4] that yielded a Ir-Ir double bonded compound [(Cp*Ir)(2)H-3][B(OH)(4)], 7. All the new compounds have been characterized by IR, H-1, B-11, C-13 NMR spectroscopy, and the molecular structures were unambiguously established by X-ray diffraction analysis.
