Abstract:
The asymmetric unit of the title compound, C20H18N2O2, contains two independent mol-ecules in which the dihedral angles between the naphthalene ring system [r.m.s. deviations = 0.012 (1) and 0.015 (1) Å] and the benzene ring are 71.65 (6) and 74.51 (6)°. In the crystal, pairs of N-H⋯O hydrogen bonds form two independent inversion dimers with graph-set notation R 2 (2)(14). In addition, each mol-ecule contains an intra-molecular O-H⋯N hydrogen bond with an S(6) motif.
