Two New Carbaalanes: Compounds with an Al(7)C(5) and a
The hydroalumination of aluminum ethynides leads to the formation of carbaalanes as a new class of compounds, which have clusters exclusively formed by carbon and aluminum atoms. Two novel carbaalanes with Al(7)C(5) and Al(7)C(4) clusters are described-the latter is a remarkable analogue of closo-[B(11)H(11)](2-) with respect to its structure and the number of cluster electrons.
