RESUMO
In the title Schiff base mol-ecule, C29H28N2O3, the three terminal benzene rings are twisted by 73.84â (15), 81.25â (16) and 12.1â (2)° with respect to the central benzene ring. An intra-molecular O-Hâ¯N hydrogen bond occurs. In the crystal, mol-ecules are linked via weak C-Hâ¯π inter-actions into a three-dimensional supra-molecular architecture.
RESUMO
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 85.5â (1) and 82.3â (1)° in the first mol-ecule, and 49.0â (1) and 40.4â (1)° in the second. This conformational difference is reflected in the central C=N-C C torsion angle, which is 28.7â (2)° in the first mol-ecule and -29.8â (3)° in the other. In each mol-ecule, there is an intra-molecular O-Hâ¯N hydrogen bond.
