Abstract
The novel chelates ML2 (M = Co, Ni, Cu, Zn) were obtained by the interactio n of 3-benzoyl-4-hydroxy- 1,2-benzothiazine-4(3H)-on-1, 1-dioxide and 2-met hyl-3-benzoyl-4-hydroxy-1,2-benzothiazine-4(3H)-on-1,1-dioxide with element al metals (direct electrochemical synthesis) or their acetates (chemical sy nthesis) in methanol. The tetrahedral or polymeric-octahedral structures wi th a beta -diketonate fragment are assigned based on IR and H-1 NMR spectra . The studied ligands and their complexes are model compounds of molecules used as anti-inflammatory drugs.
