THE RESUME On the dissertation author's abstract on competition of a scientific degree of a Cand.Chem.Sci. on a speciality «02.00.01 – Inorganic chemistry» Кolpek Аinаgul COORDINATION COMPOUNDS OF SALTS OF MANGANESE WITH THE PROTONIZED CARBAMIDE Urgency of a theme of research. One of actual problems of inorganic chemistry still has a problem of synthesis and studying of a structure, properties of the compounds which are of interest for the theory and practice. The important role thus belongs to chemistry of coordination compounds with organic ligands, being one of actual directions of a modern chemical science and technology. The coordination compounds containing salts of biometals, amides have a special place. Regular studying of processes and products of interaction of salts of metals, inorganic acids with amides has allowed establishing formation of a considerable quantity of the double compounds possessing a wide spectrum of useful qualities found application in the industry, agriculture, organic synthesis and medicine. The work purpose was regular research of processes and products of interaction of salts of manganese with the protonized carbamide in water solutions a solubility method at 25 0С and definition of physical and chemical properties of the received compounds. Into the research problem entered: solubility studying in four-componental systems manganese salt – inorganic acid – a carbamide – water; establishment of structures of formed new compounds, definition of optimum conditions of their formation; establishment of laws of mutual influence of components in the studied systems; identification of the synthesized compounds by chemical, physical and physical and chemical methods of research; research of a structure of the synthesized compounds. Scientific novelty of research. In dissertational work for the first time: solubility is studied at 25 0С in six four-componental systems containing salt of manganese – a carbamide – acid – water; in them the compounds which existence has been earlier established at studying of solubility of making three-componental systems, and also 19 new coordination compounds containing in the structure simultaneously initial components are formed; laws of mutual influence of components in the studied systems, character of dissolution of formed coordination compounds are established; optimum conditions of synthesis in laboratory conditions of 19 new compounds are developed; identification of new coordination compounds by chemical, X-ray analysis methods, by definition of temperatures of fusion (decomposition), density and solubilities in organic solvents is spent; geometrical, power and electronic parameters of some coordination compounds on the basis of spent quantum – chemical calculations are defined. The substantive provisions which are taken out on protection: solubility of chloride (bromide, iodides, perchlorate, sulphate, nitrate) of manganese, their compounds with a carbamide, and also compounds of a carbamide with hydrogen bromide, hydrogen iodide, chloric, sulfuric nitric acids in solutions of corresponding acids and the salts containing a carbamide at 25 0С; laws of complexing processes in systems chloride, bromide, iodide, sulphate, nitrate of manganese – a carbamide – hydrogen chloride (hydrogen bromide, hydrogen iodide, chloric, sulfuric, nitric) acid – water at 25 0С; techniques of synthesis of 19 new coordination compounds of salts of manganese with the protonized carbamide and results of identification by their chemical, X-ray analysis methods, physical and chemical properties of the synthesised compounds; prospective structure and geometrical parametres of some coordination compounds. Results of research: 1. On the basis of solubility studying in 6 four-componental systems containing water solutions of chloride (bromide, iodide, perchlorate, sulphate, nitrate) of manganese, hydrogen chloride, hydrogen bromide, hydrogen iodide, chloric, sulfuric, nitric acids, at 25 0С formation in these systems of 19 new coordination compounds containing simultaneously in the structure of salt of metals, a carbamide and acid is established. 2. From the analysis of the received isotherms of solubility follows, that, in most cases solubility of threefold compounds increases with growth of the maintenance of acids in a solution, i.e. is shown salting influence to what reduction of values of water number in these solutions with growth of concentration of acids testifies; there is a crystallization of ephtonical structures and the double coordination compounds which existence has been established at solubility studying in making three-componental systems manganese salt – a carbamide – water, a carbamide – acid – water; increasing quantities of acids render salting action on solubility of compounds of salts of metals with a carbamide; introduction of salts of manganese renders salting action on solubility carbamide acids; solubility ephtonical structures of systems metal salt – a carbamide – water at acid addition increases; solubility ephtonical structures of systems a carbamide – acid – water in most cases decreases with growth of concentration of initial salt of metal; growth of concentration of acids in the solutions which are in balance with initial salt leads to decrease in their solubility.
4. For the synthesized compounds temperatures of fusion (decomposition), density, solubility in a number of organic solvents are defined. The received compounds are insoluble in benzene and toluene, it is bad solved in ethoxy ethane, and it is good solved in acetone and ethanol. Density of salts of metals with the protonized carbamide has intermediate values between density of a carbamide and salts of metals. 5. As a result of tests of some synthesized compounds it is revealed, that they promote increase of productivity of plants on 20 – 40 % and do not render harmful influence on quality of a crop. 6. Displacement of strips in infra-red spectrum of valency fluctuations C = O bond in low-frequency area, C – N bonds in high-frequency area, occurrence in spectra of compounds of strips of absorption OH – groups testifies about protonized carbamide on atom of oxygen carbonyl groups. 7. Quantum – chemical calculations establish geometrical, power and electronic parametres of compounds of the structure,  the found parameters will well be agreed with infra-red spectrum researches. On structure and structure of coordination compounds considerable influence renders protonized carbamide.
Estimation of completeness of decisions of tasks in view. The problems put in dissertational work, are solved completely. As a result of the spent researches solubilities in four-componental systems manganese salt – inorganic acid – a carbamide – water are studied, structures of 19 new compounds are established, optimum conditions of their formation are defined, laws of mutual influence of components in systems are established, the synthesised compounds chemical, physical and physico – chemical methods of research are identified, revealed a structure and features of their power characteristics of thermodynamic stability. Recommendations about concrete use of results of research. Data on solubility in the studied systems give the necessary information for a choice of optimum conditions of synthesis of new coordination compounds. Physico – chemical characteristics of new compounds are supplemented with help data on coordination compounds. The obtained data bring the contribution to inorganic, coordination chemistry, chemistry of hydrogen bridges. Results quantum – chemical calculations can be used as indexes at an estimation of relative reactionary ability of a carbamide, carbamide complexes of manganese and they are recommended as help data. жүктеу/скачать 0.84 Mb.
