2-[(E)-(5-Amino-2,3-diphenyl-quinoxalin-6-yl)imino-meth-yl]-4-chloro-phenol.

ABSTRACT: The title Schiff base compound, C(27)H(19)ClN(4)O, features two intra-molecular O-H?N and N-H?N hydrogen bonds involving the hydr-oxy and amino groups to generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak inter-molecular N-H?O and C-H?N inter-actions, together with ?-? contacts [centroid-centroid distances = 3.6294?(11)-3.6881?(11)?Å], link neighboring mol-ecules.

2-[(E)-(2,3-Dimethyl-phen-yl)imino-meth-yl]phenol.

Project description:In the title compound, C(15)H(15)NO, the almost planar 2,3-dimethyl-aniline unit and the salicyl-aldehyde group (r.m.s. deviations of 0.0156 and 0.0109 Å, respectively) are oriented at a dihedral angle of 43.69 (9)° with respect to each other.
