Abstract: The getting new DCC, examination, determination of properties of substances currently plays an important role in the development of both chemical and other industries, machinery and new technologies. The aim of this work is the synthesis, IR spectroscopic analysis, and identify basic physical and chemical properties of substances. The synthesis and IR spectroscopic analysis of the solid products of interaction hexaisothiocianatochromate (III) potassium (and also in parallel with tetraisothiocianatodiaminechromate (III) ammonium) with a 4-aminoantipyrine and salts of cobalt, nickel, manganese, iron (II). Defined and their solubility in organic and inorganic solvents and inorganic acids, as well as the melting temperature. In the course of work identied the following properties of products: the substances are double coordination compounds in which the 4-aminoantipyrine is a ligand of the cation, the coordination of which goes through the nitrogen atom and the oxygen atom at the same time. Also identified coordination of the cation and anion. Established stability of the solid products of the interaction hexaisothiocianatochromate (III) potassium (and also in parallel with tetraisothiocianatodiaminechromate (III) ammonium) with a 4-aminoantipyrine and salts of cobalt, nickel, manganese, iron (II) and their solubility in organic and inorganic solvents, and inorganic acids. Installed the melting temperature of the two solids.

Key words: synthesis IR spectroscopic analysis method 4-aminoantipyrine cobalt nickel manganese iron(II)
