Reaction of 3-formylsalicylic acid with 2-aminobenzenethiol yielded 2-(1-carboxyl-2-hydroxyphenyl)benzothiazoline, H 2 chpbzn, rather than the corresponding Schiff base, 2-(2-mercaptophenyl)(3 0 -carboxy)salicylaldimine, H 3 mpcsalim. The reaction of H 2 chpbzn with (p-C 5 H 5 ) 2 TiCl 2 , (p-C 5 H 5 ) 2 ZrCl 2 , CrCl 3 Á6H 2 O, FeCl 3 (anhydrous), VOSO 4 , VOCl 3 , Ni(OAc) 2 Á4H 2 O, Na 2 PdCl 4 , Me 2 TlCl, Ph 2 TlCl, BiCl 3 and SbCl 3 , under varied reaction conditions, afforded the corresponding Schiff base complexes of the metal ions. For all of the complexes, except those of bismuth and antimony, the dianion of the Schiff base acts as a tridentate NSO donor ligand, while in the bismuth and antimony complexes the neutral benzothiazoline functions as a monodentate N donor ligand.
