Subjects of research: nikotinates Co (II), Ni (II), Си (II), Zn, acetamide, carbamide, thiocarbamide, nicotinamide, nicotinic acid, plant growth stimulators.
Purpose of work: To synthesize new mixed ligand of coordination compounds of nikotinates of some metals. To establish their structure, individuality, reactionary ability, structures, definition of physical, chemical, biological properties. To choose biologically more active compounds and recommend them as a stimulator of cotton growth.
Methods of research: The differential thermal analysis, X-Ray phase analysis, infra red spectrum of absorption, diffuse spectrum of reflection, methods of quantum chemical calculation.
The results obtained and their novelty: 32 new mixed amidonikotinates complex compounds of some metals have been synthesized with acetamide, carbamide, thiocarbamide, nicotinamide and nicotinic acid. Composition, individuality and structures have been determined. For some compounds, the electronic structures have been investigated with the help of quantum chemical methods. On the basis of biological researches new effective stimulator of cotton growth have been found.
Practical value: New effective stimulator of cotton growth of multifunctional action Zn-11 has been discovered.
Degree of embed and economical effectivity: The stimulator Zn-11 have been tested for 5 years by the way of soaking cotton seeds with 0,002 % aqueous solution of the preparation on the experimental fields of the scientific-research institute of cotton production of Uzbekistan, Bukhara and in Khorezm branch the scientific-research institute of cotton production of Uzbekistan.
Field of application: chemistry of coordination compounds and agriculture.
