Bis(oxotremorine) fumarate bis­(fumaric acid)

ABSTRACT: In the title mol­ecular salt, 2C12H19N2O+·C4H2O42−·2C4H4O4, the components are held together by N—H⋯O and O—H⋯O hydrogen bonds, forming chains along [001]. The title compound, bis­(oxotremorine) fumarate bis­(fumaric acid) {systematic name: 1-[4-(2-oxopyrrolidin-1-yl)but-2-yn­yl]pyrrolidinium (2E)-but-2-ene­di­o­ate bis­[(2E)-but-2-enedioic acid]}, 2C12H19N2O+·C4H2O42−·2C4H4O4, has a single oxotremorine monocation protonated at the pyrrolidine nitro­gen, one fumaric acid mol­ecule and half of a fumarate dianion in the asymmetric unit. The ions and fumaric acid mol­ecules are held together by N—H⋯O and O–H-⋯O hydrogen bonds in 40-membered rings with graph-set notation R66(40). The fumarate ions join these rings into infinite chains along [001].
