Abstract
In supercritical ammonia, the stepwise dehydrogenation of [H2GaNH2](3) to nanocrystalline GaN at 150 degrees C requires several hours and pr oceeds through the new crystalline 2-D polymeric compound, poly(imidog allane), [HGaNH](n), which can be isolated in high yield after 30 min of reaction. Use of ND3 results in rapid exchange of the NH2 ligands i n [H2GaNH2](3) with ND2, even at -33 degrees C, suggesting that a dono r-acceptor complex, H2Ga(NH2)(NH3), is present in solution.
