A new benzothiazoline derivative, 3-(2,3-dihydro-1,3-benzo- thiazol-2-yl)quinoxalin-2(1H)-one, has been synthesized by the reaction of 3-hydroxyquinoxaline-2-carboxaldehyde with 2-mercaptoaniline. Its complexation with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) ions proceeds with the rearrangement of benzothiazoline ring to form the corresponding Schiff base chelates. The quinoxaline moiety of the
