New beta-aminovinylketones with heterocyclic 1,2-benzothiazine-1,1-dioxide and antipyrine moieties (LH) and their 3d-metal (Co-II, Ni-II, Cu-II, Zn-II) chelates have been synthesized. Two types of chelates can be obtained based on the coordination of the LH ligand, depending when an available carbonyl (C=O) group of the antipyrine fragment is coordinated (M = Co, Ni) or not (M = Cu) to the metal center. The molecular structure of compound 5b was obtained by X-ray diffraction, indicating that the ligand 2b forces the complex to adopt a highly distorted tetracoordinate square planar structure. Details on the synthesis and characterization of these complexes are discussed. (C) 2004 Elsevier Ltd. All rights reserved.
