Publisher: De Gruyter Abstract The crystal structures of two (E)-2-(2-benzylidenehydrazin-1-yl)quinoxaline derivatives, (E)-2-(XYC6 H3-CH=N-NH)-quinoxalines, 1, namely (1: X=H; Y=4-MeO or 4-O2 N) have been determined. In both cases, the major intermolecular interactions are N–H···N(pyrazine) hydrogen bonds. While in […]
