2-{(E)-[4-(Di-phenyl-amino)-phen-yl]imino-meth-yl}phenol.

ABSTRACT

The asymmetric unit of the title Schiff base molecule, C25H20N2O, contains two independent mol-ecules. In each mol-ecule, the C=N bond is in an E conformation. The most significant difference between the two mol-ecules is seen for the dihedral angles between the meth-oxy-substituted benzene ring and the two phenyl rings, which are 85.5 (1) and 82.3 (1)° in the first mol-ecule, and 49.0 (1) and 40.4 (1)° in the second. This conformational difference is reflected in the central C=N-C C torsion angle, which is 28.7 (2)° in the first mol-ecule and -29.8 (3)° in the other. In each mol-ecule, there is an intra-molecular O-H⋯N hydrogen bond.
