Ethyl (2E)-2-cyano-3-(1-methyl-1H-pyrrol-2-yl)prop-2-enoate

Abstract

The 15 non-H atoms of the title compound, C 11H 12N 2O 2, are approximately coplanar, the r.m.s. deviation being 0.145 Å. The major deviation from coplanarity is seen in a twist between the ethene (E configuration) and pyrrole rings [C - C - N - C torsion angle = -8.26 (18)°]. The carbonyl O and cyano N atoms are syn to each other. In the crystal, supramolecular linear tapes linked by C - H⋯O and C - H⋯N interactions are further connected by C - H⋯π(pyrrole) interactions.
