A new coordination polymer Zn(II) with thiosemicarbazone glyoxalic acid H2GAT was obtained in this study. According to the X-ray diffraction data, the coordination of the Zn(II) ion is carried out by one sulfur atom, in the thiol form, one nitrogen atom of the azomethine group and two oxygen atoms of the carboxylate groups, one of which belongs to neighbouring complex molecule. The oxygen atom of the water molecule completes Zn(II) ion environment to a distorted square-pyramidal structure. The binding of the monomer complex into polimer occurs through the bridge oxygen atom of carboxylate group. This complex is effective inhibitor of the alpha-glycosidase, butyrylcholinesterase (BChE), cytosolic carbonic anhydrase I and II isoforms (hCA I and II), and acetylcholinesterase enzymes (AChE) enzymes with Ki values of 1.45+/-0.23microM for hCA I, 2.04+/-0.11microM for hCA II, 3.47+/-0.88microM for alpha-glycosidase, 0.47+/-0.10microM for BChE, and 0.58+/-0.13microM for AChE, respectively.
