title: (Z)-N-(2,6-Diiso-propyl-phen-yl)-4-nitro-benzimidoyl chloride.
abstract: In the title compound, C19H21ClN2O2, the aromatic rings are approximately perpendicular to each other, subtending a dihedral angle of 87.7 (1)°. In the crystal, the 4-nitro-phenyl groups of pairs of neighbouring mol-ecules are parallel and oriented head-to-tail with a ring centroid-centroid distance of 3.9247 (12) Å, leading to a π-π inter-action between the pair. The faces of each phenyl ring of the 2,6-diiso-propyl-phenyl group inter-act with two different groups, viz. a chloro group of an adjacent mol-ecule on one side and the edge of the 4-nitro-phenyl ring of a second mol-ecule on the other side.
