A second monoclinic polymorph of 1-benzyl-N-methyl-1H-pyrrole-2-carboxamide

Abstract

In the title compound, C13H14N2O, the Npyrrole—C(H2)—C—C torsion angle is −7.7 (3)° and the dihedral angle between the pyrrole and benzene rings is 83.6 (2)°. In the crystal, intermolecular N—H...O hydrogen bonds link the molecules into chains extending along the c axis. We have previously reported another polymorphic form of this title compound, which has the same space group with different cell parameters: a = 9.8285 (18) Å, b = 23.588 (4) Å, c = 9.9230 (17) Å, β = 90.107 (3)°, Z = 8 and V = 2300.5 (7) Å3 [Zeng et al. (2010). Acta Cryst. E66, o2051].
