As a result of the conducted research work the methods of synthesis of new mono-, bis- and polychelating phosphoryl ligands of carbacylamidophosphate and sulfonamidophosphate types, transamination of aminocarboxylic acids, selective nitration of 4,4'-bipyrazole, as well as the synthesis of hybrid inorganic-organic compounds and complexes based on 3d / 4f-metals. The functional properties of the obtained compounds are studied, the ways of their possible practical application are outlined. Among the synthesized according to the developed and tested methods of synthesis of new mono-, bis- and polychelating phosphoryl ligands of carbacylamidophosphate (CAF) and sulfonylamidophosphate (SAF) types, promising complexing agents with the properties of antenna ligands have been identified. It has been shown that the introduction of exodorant groups into polychelating ligands makes them attractive objects for the synthesis of polynuclear homo- and heterometallic complexes. Methods of selective nitration of 4,4'-bipyrazole and transamination of aminocarboxylic acids to obtain organic ligands with donor groups of 1,2,4-triazole and carboxylic acid, which are separated by a hydrogencarbon spacer of different shapes and lengths, have been developed and tested. Obtained and identified organic and inorganic salts from nitro derivatives of 4,4’-bipyrazole, as well as coordination polymers and inorganic-organic hybrids based on MoO3 with 1,2,4-triazolecarboxylic acids, the conditions of their crystallization were established. Formation conditions were studied, synthesis parameters were determined and synthesis methods were developed, according to which 3d-metal complexes with o-vanillin or 2-pyridinecarbaldehyde-based ligands and various Cu / W complexes with N, N-donor ligands were obtained and identified.
