Abstract:
Cocrystallization of 4-carboxypiperdine with 5-nitro-isophthalic acid afforded the title salt, 2C(6)H(12N)O(2) (+)·C(8)H(3)NO(6) (2-), in which the heterocyclic N atoms are protonated and the carboxylic acid groups are deprotonated. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen-bonding inter-actions assemble the ions into a three-dimensional network.
