چکیده

In the title compound, C(16)H(18)N(2)O(2), the mol-ecule adopts an E conformation about the C=N double bond. The dihedral angle between the pyrrole and phenyl rings is 41.55 (8)°. In the crystal structure, pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. In the dimer, the two pyrrole rings are almost coplanar and the two phenyl rings are parallel to each other.

The non-H atoms of the title compound, C(9)H(13)NO(2), are almost coplanar (r.m.s. deviation = 0.0358 Å). Weak inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the b axis with graph-set motif C(5). The chains are further linked into a three-dimensional network by C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
