Crystal structure of 2-aza-niumyl-3-bromo-6-oxo-5,6-di-hydro-pyrido[1,2-a]quinoxalin-11-ium dibromide.

ABSTRACT: The title salt, C12H10BrN3O(2+)·2Br(-), was synthesized from the reaction of N (1),N (4)-bis-(pyridin-2-yl-methyl-idene)benzene-1,4-di-amine and bromine in a methanol solution. All non-H atoms of the 2-aza-niumyl-3-bromo-6-oxo-5,6-di-hydro-pyrido[1,2-a]quinoxalin-11-ium cation are nearly coplanar, the maximum deviation being 0.114?(4)?Å. In the crystal, the cations and anions are linked through N-H?Br hydrogen bonds and weak C-H?Br inter-actions, forming a three-dimensional supra-molecular architecture. A short Br?Br contact [3.3088?(9)?Å] is observed in the crystal.
