title: Dicyclo-hexyl-ammonium hydrogen phenyl-phospho-nate.
abstract: In the title salt, [(C(6)H(11))(2)NH(2)](+)·[C(6)H(5)PO(2)(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 inter-actions, forming inversion dimers with R(2) (2)(8) ring motifs. These dimers are bridged by two dicyclo-hexyl-aminium cations via pairs of N-H⋯O hydrogen bonds, giving R(4) (4)(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C-H⋯O inter-actions, forming a two-dimensional network lying parallel to (101).
