Cytenamide-butyric acid (1/1)

Abstract

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