摘要：
Two new structural isomeric ligands, 2-(indazol-1-yl)-2-thiazoline (TnInA) (1) and 2-(indazol-2-yl)-2-thiazoline (TnInL) (2), have been prepared and characterized by a variety of physico-chemical techniques. Likewise, the cadmium (II) complexes [Cd(NO3)(2)-(TnInA)(2)] (3) and [Cd(NO3)(2)(TnInL)(2)] (4) have been isolated and characterized through elemental analysis, IR and UV-Vis spectroscopy. Moreover, the structures have been determined by X-ray diffraction. Both ligands act as bidentate ligands through thiazoline nitrogen atom and indazole nitrogen atom, making a five-membered chelate ring. The environment around the cadmium (II) atom in both complexes may be described as a triangulated dodecahedral geometry. (c) 2005 Elsevier Ltd. All rights reserved.
