Derivatives of B6H10, in which a R3M group [M = Sn, R = Ph (I), Me (II)} replaces a bridging hydrogen atom, have been prepared and characterized by NMR spectroscopy. The bridging H atoms, in the 2,3-μ-(R3M) - B6H9 species, are fluxional on both the boron-11 and proton NMR time scale, but the motion appears to be partially quenched as observed for other 2,3-μ-metalla derivatives of hexaboranes. At temperatures above about -10°C some simple motion of the cage relative to the R3Sn group is invoked to account for the spectra of I. 2,3-μ-(Me3Sn)B6H9 is unstable and could not be isolated or handled at temperatures above ca. -20°C.
