It is known that thiosemicarbazide and its derivatives form the stable coordination compounds with virtually all transition metals. Many of these compounds are biologically active, a property that allows their use as a base for selective microbiological culture media and makes them promising for application as disinfectants and antiseptics. In many cases, the biological activity of drugs is correlated with their complexation capacity. Therefore, the synthesis and investigation of new biometal complexes with different ligands are of both scientific and practical interest. In this study we report on the crystal structures of two forms of nitrato-{2-[2-(1-pyridin-2yl)ethylidene]hydrazinyl}-benzothiazolоcopper (I and II). The complexes of I and II were extracted from reaction mixture due to interaction of cooper trihydrate with {2-[2-(1-pyridin-2yl)ethylidene]hydrazinyl}benzothiazolе. The coordination polyhedrons of the central atoms in both complexes are the elongated tetragonal bipyramids, but the complex I (Fig. 1) is monomer while in the crystal the complexes II (Fig. 2) are joined by nitrate groups in polymeric chains.figure 1Fig. 1.
