1,1′-Dimethyl-1,1′-(butane-1,4-diyl)dipyrrolidinium dibromide methanol disolvate
Abstract
In the title compound, C14H30N22+·2Br−·2CH3OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methylpyrollidines, 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 molecule. In the crystal structure, the bromide anions are linked to the methanol solvent molecules by O—H...Br hydrogen bonds.
