A new ligand N-(5,6-dihydro-4H-1,3-thiazin-2-yl)indazole (InTz) and its metal complexes [Co(NO 3 ) 2 (InTz) 2 ] and [Cd(NO 3 ) 2 (InTz) 2 ] have been prepared and characterized by a variety of physico-chemical techniques. Likewise, the structures have been determined by X-ray diffraction. Metal complexes have C 2 symmetry. The environment around the cobalt atom may be described as a distorted octahedral geometry with the metallic atom coordinated to two oxygen atoms from two monodentate nitrate groups, two thiazine nitrogen atoms and two indazole nitrogen atoms. The cadmium complex consists of molecules in which the cadmium atom is eight coordinated, with two bidentate nitrate groups and two bidentate InTz ligands, each of the latter having one thiazine and one indazole nitrogen atom involved in coordination. The geometry around the cadmium atom is adequately described as a distorted dodecahedron.
