Crystal structure of 2-cyano-N'-(cyclo-hexyl-idene)acetohydrazide.

ABSTRACT: In the title compound, C9H13N3O, the cyclo-hexyl-idene ring adopts a chair conformation and the bond-angle sum at the C atom linked to the N atom is 359.6°. The cyano-acetohydrazide 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 inter-actions, which generate R 2 (2)(14) loops. The dimers are linked by C-H?Nc (c = cyanide) inter-actions into [100] ladders, which feature C(4) chains and R 4 (4)(20) loops.
