Abstract
The structure of a gallium tribromide complex with 2-aminomethylpyridine (amPy) (1: 1) has been established by single-crystal X-ray diffraction for the first time. The complex has been shown to have the ionic structure [GaBr(2)amPy(2)](+)[GaBr4](-) in the condensed phase.

Abstract
The structure of a gallium tribromide complex with 2-aminomethylpyridine (amPy) (1: 1) has been established by single-crystal X-ray diffraction for the first time. The complex has been shown to have the ionic structure [GaBr(2)amPy(2)](+)[GaBr4](-) in the condensed phase. The qualitative composition of the vapor over the complex has been determined by mass spectrometry within a temperature range of 80-250A degrees C. The elimination of hydrogen bromide and 2-aminomethylpyridine proceed at 80-180A degrees C to enrich the condensed phase with gallium tribromide. GaBr2(amPy-H), GaBr(3)amPy, GaBr(amPy-2H), and Ga2Br5(amPy-H) are the major gallium-containing vapor species at 250A degrees C.
