[en] New complex compound with tryptophane of the complexes [Zn(trp)₂(H₂O)₂] were synthesized. It is shown that the composition of the complex obtained depends on the ratio of the initial components. The composition and structure of the complex were studied by elemental analysis, IR, X-ray phase analysis and thermogravimetric analysis. The method of IR spectroscopy showed that the ligand in the complex of the metal (II) complexes enter the neutral form and coordinate with the complexing agent through the nitrogen atom. The results of thermogravimetric studies have shown that the final product of the thermal decomposition of all compounds is metal oxide, respectively. The effect of the zinctryptophan complex (Zn-trf) on the biosynthesis of photosynthetic pigments and morphological parameters of seedlings of irradiated wheat seeds was studied. Initial experiments showed that, when treated seeds with the (Zn-trf) complex, their resistance to gamma rays is increased. On the basis of the data obtained, it can be concluded that the complex (Zn-trf) has radio protective properties
