title: Cytenamide-butyric acid (1/1).
abstract: Cytenamide forms a 1:1 solvate with butyric acid [systematic name: 5H-dibenzo[a,d]cyclo-hepta-triene-5-carboxamide-butanoic acid (1/1)], C(16)H(13)NO·C(4)H(8)O(2). The title compound crystallizes with one mol-ecule of cytenamide and one of butyric acid in the asymmetric unit; these mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds to form an R(2) (2)(8) heterodimer motif. Pairs of adjacent motifs are further connected via N-H⋯O inter-actions to form a discrete centrosymmetric assembly.
