Aim. The synthesized and characterized of the complex nickel (II) with tryptophan [NiL2 (H2O)2]; L = Trp. It is shown that the composition of the complex obtained depends on the ratio of the initial components. Methods. The composition and structure of the complex were studied by elemental, TG/DrTG-DTA analysis and IR spectroscopy. The method of IR showed that the ligand in the composition of the metal complex enter the neutral form and coordinate with the complexing agent through the nitrogen atom. Results. The results of thermogravimetric studies have shown that the final product of the thermal decomposition of all compound is metal oxide, respectively. Conclusions. Have been studied the biological properties – the toxicity has been evaluated, the influence of the complex on the resistance to hypoxia and ant radiation activity has been determined.

Keywords: tryptophan, nickel, tryptophan-metal complexes, amine groups, IR spectroscopy, thermogravimetry, toxicity, antiradiation activity.
