Abstract
The title compound, C16H19N3O2, exhibits a trans geometry about the N=N double bond in the triazene unit in the solid state, and individual molecules are close to planar with r.m.s. deviations from planarity of 0.065 Å and 0.242 Å for the two independent molecules in the asymmetric unit. Distinct intermolecular N—H⋯N hydrogen bonds lead to the formation of dimers with an R 2 2(8) graph-set motif. The steric demands of the ethoxy groups in the ortho position prevent a coplanar arrangement of the two molecules in the dimers and these instead consist of two interlocked molecules that are related by a non-crystallographic pseudo-twofold rotation axis. Weak C—H⋯π interactions between the CH groups and the aromatic phenyl rings also occur.
