Hydrogen-Rich Derivatives of Gallane

The infrared spectra of natural and perdeuteriated samples of galla-borane imply the presence of a molecular unit common to the vapor and matrix-isolated states. The results advance strong circumstantial evidence that the molecule is H2Ga(p-H)2BH2 (8) with a bidentate 

Metathesis with tetra-n-butylammonium octahydrotriborate, [Bun4N]+[B3H8] , at temperatures near 243 K converts monochlorogal-lane into gallatetraborane, GaB3H10, in yields not far from those implied by
