Ethyl (E)-2-cyano-3-(4-methylphenyl)acrylate: a second monoclinic polymorph
The title compound, C(13)H(13)NO(2), was previously described in space group P2(1)/c by He et al. [Acta Cryst. (1993), C49, 2000–2002]. The ethyl group is disordered over two sets of sites in a 0.615 (10):0.385 (10) ratio. The C—O—C—C torsion angles containing the ethyl group are −111.6 (10) and 177...

description | The title compound, C(13)H(13)NO(2), was previously described in space group P2(1)/c by He et al. [Acta Cryst. (1993), C49, 2000–2002]. The ethyl group is disordered over two sets of sites in a 0.615 (10):0.385 (10) ratio. The C—O—C—C torsion angles containing the ethyl group are −111.6 (10) and 177.9 (7)°, while in the previously reported polymorph, the torsion angle is −167.3 (2)°. The molecules pack to form a three-dimensional structure in the ABAB style along the c-axis direction in the title compound, but parallel to the a-axis direction in the reported polymorph. |
