Abstract
The title compound [systematic name: 4-diphenylmethyl-1-(3-phenylprop-2-en-1-yl)-piperazin-1-ium 2-carboxy-4,6-dinitrophenolate], C26H29N2 +·C7H3N2O7 −, is the dinitrosalicylate salt of a tertiary amine. Deprotonation of the carboxylic acid group occurred on the phenolic hydroxy group. The diazacyclohexane ring adopts a chair conformation. Intramolecular O—H⋯O and intermolecular C—H⋯O and N—H⋯O hydrogen bonds are observed. The N—H⋯O hydrogen bonds are bifurcated at the H atom and connect the cinnarizinium and 3,5-dinitrosalicylate ions together. Intermolecular C—H⋯O hydrogen bonds connect the components into layers perpendicular to the crystallographic a axis.
