The formation of trimethylphosphine-hexaborane(10) in the reaction of hexaborane(10) with trimethylphosphine was confirmed. The compound is stable below -20°C in dichloromethane or in tetrahydrofuran and reacts with trimethylphosphine to give bis(trimethylphosphine)-hexaborane(10). Triphenylphosphine adds to hexaborane(10) likewise to form B6H10·P(C6H5)3. On the basis of the 11B and 1H NMR spectra, a B5H8- derivative structure is proposed for the 1:1 adducts. A mechanism for the conversion of the pyramid-shaped B6H10 framework to the belt-shaped structure of B6H10·2P(CH3)3 is discussed.
