ABSTRACT: The title hydrazide compound, C(20)H(24)N(2)O(2), exists in a trans configuration with respect to the acyclic C=N bond and an intra-molecular O-H?N hydrogen bond generates an S(6) ring motif. The mean plane through the formohydrazide unit is essentially planar [maximum deviation = 0.025?(2)?Å], and forms dihedral angles of 24.45?(16) and 87.14?(16)° with the two benzene rings. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link neighbouring mol-ecules into extended chains along the c axis, which incorporate R(2) (2)(16) ring motifs. An inter-molecular C-H?? inter-action is also observed.
