Abstract

Two complexes [CuII(pbt)(dmf)Cl2] and [FeIII(pbt)Cl3], where pbt is 2-(2-pyridyl)benzothiazole, and dmf is dimethylformamide, were prepared by the reaction of metal chlorides with pbt solutions. The structures of the products were identified by elemental analysis, usual spectroscopic methods and X-ray diffraction analysis. The crystal data revealed penta-coordination around both metal ions, with trigonal bipyramidal geometries. 2-(2-pyridyl)benzothiazole binds to both CuII and FeIII in the N,N-chelation manner and leaves the S atom uncoordinated.
