Abstract

In the title compound, C9H13N3O, the cyclohexylidene ring adopts a chair conformation and the bond-angle sum at the C atom linked to the N atom is 359.6°. The cyanoacetohydrazide grouping is close to planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and subtends a dihedral angle of 64.08 (4)° with the four C atoms forming the seat of the chair. The C=O and N - H groups are in a syn conformation (O - C - N - H = -5°). In the crystal, inversion dimers linked by pairs of N - H⋯O hydrogen bonds generate R 2 2(8) loops; this dimer linkage is reinforced by a pair of C - H⋯O interactions, which generate R 2 2(14) loops. The dimers are linked by C - H⋯Nc (c = cyanide) interactions into [100] ladders, which feature C(4) chains and R 4 4(20) loops.
