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

ABSTRACT: The title compound, C(27)H(19)BrN(4)O, is a mono-anil Schiff base ligand. Three intra-molecular O-H?N and N-H?N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak inter-molecular N-H?O and C-H?O hydrogen bonds together with ?-? inter-actions [centroid-centroid distances = 3.628?(3)-3.729?(3)?Å] link neighboring mol-ecules.

The title compound, C(27)H(19)BrN(4)O, is a mono-anil Schiff base ligand. Three intra-molecular O-H⋯N and N-H⋯N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak inter-molecular N-H⋯O and C-H⋯O hydrogen bonds together with π-π inter-actions [centroid-centroid distances = 3.628 (3)-3.729 (3) Å] link neighboring mol-ecules. ...[more]
