Abstract:
The title compounds, 3,4-dimethyl- N -[1-(1 H -pyrrol-2-yl)ethylidene]aniline, C 14 H 16 N 2 , (I), and its analogue 3,4-dimethyl- N -[1-(1-thiophen-2-yl)ethylidene]aniline, C 14 H 15 NS, (II), both have basic heterocyclic imino structures showing a planar backbone with similar features, but differing in the heteroatoms of the five-membered heterocyclic rings, i.e. N in (I) and S in (II). The dihedral angles formed by the five-membered and benzene rings are 81.78 (8) and 75.89 (7)° for (I) and (II), respectively. In (I), centrosymmetric iminopyrrole dimers are assembled by means of two inverted N—H...N hydrogen bonds and two inverted C—H...π interactions. In (II), however, molecules are linked by nonclassical C—H...N hydrogen bonds in which the molecules act as both hydrogen-bond donors and acceptors, resulting in one-dimensional supramolecular chains.
