Two complexes [Cu
II(pbt)(dmf)Cl
2] and [Fe
III(pbt)Cl
3], 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 Cu
II and Fe
III in the N,N-chelation manner and leaves the S atom uncoordinated.
