1,1'-Dimethyl-1,1'-(butane-1,4-di-yl)dipyrrolidinium dibromide methanol disolvate.


ABSTRACT: In the title compound, C(14)H(30)N(2) (2+)·2Br(-)·2CH(3)OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methyl-pyrollidines, forming a linear diquaternary ammonium cation. The cation lies across a centre of inversion located between the two central C atoms of the butane chain. The asymmetric unit therefore comprises one half-cation, a bromide anion and a methanol solvent mol-ecule. In the crystal structure, the bromide anions are linked to the methanol solvent mol-ecules by O-H?Br hydrogen bonds.
