Unprecedented gallium–nitrogen anions: synthesis and characterization of [(Cl3Ga)3N]3− and [(Cl3Ga)2NSnMe3]2−

Abstract

The [(Cl₃Ga)₃N]³⁻ (1) anion, which is the sole example of a discrete chemical species containing a μ₃-N atom bound only to gallium, was isolated from the reaction of Cl₃Ga·N(SnMe₃)₃ with [GaCl₄]¹⁻. The analogous reaction of [GaCl₄]¹⁻ with (Me₃Sn)₃N afforded [(Cl₃Ga)₂NSnMe₃]²⁻ (2), which is also an unprecedented anion containing a single μ₃-N atom bound to only gallium and tin.
