Ethane-1,2-diaminium 3,4,5,6-tetra-bromo-2-(methoxy-carbon-yl)benzoate methanol solvate

, : Ethane-1,2-diaminium 3,4,5,6-tetra-bromo-2-(methoxy-carbon-yl)benzoate methanol solvate. Acta Crystallographica. Section E, Structure Reports Online 64(Pt 12): O2416-O2416

In the title compound, C(2)H(10)N(2) (2+)·2C(9)H(3)Br(4)O(4) (-)·CH(4)O, the N atoms of the ethane-1,2-diamine mol-ecule are protonated. The crystal structure is stabilized by N-H⋯O hydrogen bonds between the ethane-1,2-diaminium cations and 3,4,5,6-tetra-bromo-2-(methoxy-carbon-yl)bromo-benzoate anions, and by O-H⋯O and N-H⋯O hydrogen bonds between the methanol solvate and both the cation and the anion. In addition, the crystal structure exhibits a C-Br⋯O halogen bond [3.20 (3) Å] and a Br⋯Br inter-action [3.560 (2) Å].
