(E)-2-[4-(2-Chlorophenyl)but-3-en-2-ylidene]malononitrile
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&...

| Summary: | 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—H...N interactions that connect the independent molecules into supramolecular chains along the c-axis direction. |
