Decomposition of monochlorogallane,[H2GaCl] n, at ambient temperatures gives the mixed valence compound Ga [GaHCl3], which has been characterized crystallographically. Nitrogen bases cause cleavage of the Ga-Cl bridges of the parent compound, with the formation of products such as Me3N⊙ GaH2Cl and [H2Ga (NH3) 2]+ Cl-, whereas ethene inserts into the Ga-H bonds to form [Et (H) GaCl] 2 and [Et2GaCl] 2.
