The study of the synthesis and crystallochemistry of coordination compounds, especially supramolecular complexes, is the basis for researchers working in this field. as one of the fields of scientific research currently maintains its importance. Such supramolecules are widely used as laser materials, as catalysts in chemical technology, as well as in gas chromatography, as biologically active substances, as antimicrobial drugs in medicine [1].3,5-dinitrobenzoic acid and complex compounds of hydroxy benzoic acid with Cerium (III) and Silver (I) cations were synthesized and molecular and crystal structures were studied [2,3]. Several compounds of the adduct-forming pyrazine molecule were obtained and their structures were studied [4,5]. The electronic structure of the applied ligands and the nature of transition elements used as complexing agents play a special role in the appearance of the above properties.
It is known that in the synthesis of complex polymers with a supramolecular spatial structure (3D dimension) based on organic ligands, the nature and number of donor atoms in them is considered one of the main indicators.
