Synthesis and Epr Characterization of a Serees of 2,2′-Diamino-4,4′-Bithiazole and 2,2′-bis(acetamido)-4,4′- Bithiazole Copper(II) Complexes

Copper(II) complexes of the formula CuLX 2 , (L = 2,2′-diamino-4,4′-bithiazole or 2,2′-bisacetamido-4,4′-bithiazole, X = C1, Br, NO 3 , 1/2SO 4 ), were prepared and characterized by elemental and thermogravimetric analyses, IR, electronic and EPR spectroscopy. In all of the prepared compounds the li...

Zusammenfassung:Copper(II) complexes of the formula CuLX 2 , (L = 2,2′-diamino-4,4′-bithiazole or 2,2′-bisacetamido-4,4′-bithiazole, X = C1, Br, NO 3 , 1/2SO 4 ), were prepared and characterized by elemental and thermogravimetric analyses, IR, electronic and EPR spectroscopy. In all of the prepared compounds the ligands act in a bidentate fashion through the nitrogen atoms of the thiazole rings. The electronic and EPR spectral data show that the complexes have a tetrahedral distorted structure, except for the [CuLCI 2 ] 2 (L = 2,2′-bisacetamido-4,4′-bithiazole) complex. This dimeric complex presents two bridging chloride groups between the two non-equivalent Cu(II) ions.
