Abstract

In the title salt, [(C6H11)2NH2]+·[C6H5PO2(OH)]−, the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O—H⋯O inter­actions, forming inversion dimers with R22(8) ring motifs. These dimers are bridged by two dicyclo­hexyl­aminium cations via pairs of N—H⋯O hydrogen bonds, giving R44(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C—H⋯O inter­actions, forming a two-dimensional network lying parallel to (101).
