Dicyclohexylammonium O,O’-Diphenyl Phosphate, [-C6H11-2NH2][-C6H5O-2P-O--O-]: Spectroscopic Study, Crystal Structure, and Hirshfeld Surface Analysis

Abstract

The title salt, [-C6H11-2NH2][-C6H5O-2P-O--O-], crystallizes in the chiral space group P212121, composed of achiral cation and anion components. The strong charge-assisted N–H...O hydrogen bonds build a linear assembly along the a axis, including a non-centrosymmetric C22-6- chain graph-set motif. The intra and intermolecular C–H...O interactions as well as the C–H...π-electron ring interactions also exist in the crystal structure. Fingerprint plots are used for a detailed investigation of intermolecular interactions participating in the crystal packing. The spectroscopic features -IR, 1H NMR, 13C{1H} NMR, 31P{1H} NMR, and mass- are studied.
