The quinoxaline ring system is planar and the dihedral angle between the phenyl and piperazine rings is 28.6 (1) degrees. The crystal structure is stabilized by intermolecular C - H...O hydrogen bonds.eninfo:eu-repo/semantics/closedAccessBenzimidazoleDerivativesBenzothiazoleArticle60O1266O126810.1107/S16005368040149892-s2.0-18444376490N/AWOS:000222374500119Q4
