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.
Highlights
The charge-assisted hydrogen bonds were observed in some cation–anion compounds including phosphorus–oxygen-based anions

Summary
The charge-assisted hydrogen bonds were observed in some cation–anion compounds including phosphorus–oxygen-based anions. Structural Database (CSD) survey was investigated to compare the hydrogen bond strengths in some phosphate-based classes of salts and neutral closely related structures [4]. The chiral crystal structures from chiral or achiral molecules/components were studied, and the diversity of hydrogen bond motifs was investigated [5,6,7]. The chiral crystal structure [(C6 H11 ) NH2 ][(C6 H5 O) P(O)(O)], including achiral components, is investigated, and the synergistic cooperation of N–H . The synthesis procedure and spectroscopic characterization of the title compound are detailed. A comparison of the cation and anion components of the title salt with the structures including similar components from the CSD is presented
