Abstract: There are two independent but virtually identical molecules in the asymmetric unit of the title compound, C13H19ClN2. Each molecular skeleton displays an approximately planar structure except for the methyl group [the r.m.s. deviations for all 16 non-H atoms are 0.039 (molecule 1) and 0.056 Å (molecule 2)]. An E configuration is found about each of the C=C bonds. The crystal packing is stabilized by C-HN interactions that connect the independent molecules into supramolecular chains along the c-axis direction.
