Cytenamide forms a 1:1 solvate with butyric acid [systematic name: 5H-dibenzo[a,d]cycloheptatriene-5-carboxamide-butanoic acid (1/1)], C16H13NO·C4H8O2. The title compound crystallizes with one molecule of cytenamide and one of butyric acid in the asymmetric unit; these molecules are linked by N-HO and O-HO hydrogen bonds to form an R22(8) heterodimer motif. Pairs of adjacent motifs are further connected via N-HO interactions to form a discrete centrosymmetric assembly.
