Abstract

The title compound, C(16)H(19)N(3)O(2), exhibits a trans geometry about the N=N double bond in the triazene unit in the solid state, and individual mol-ecules 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 inter-molecular 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 eth-oxy groups in the ortho position prevent a coplanar arrangement of the two mol-ecules in the dimers and these instead consist of two inter-locked mol-ecules that are related by a non-crystallographic pseudo-twofold rotation axis. Weak C-H⋯π inter-actions between the CH groups and the aromatic phenyl rings also occur.
