Abstract
Polynuclear complex compounds of 3d metals with amino alcoholic ligands can be used to obtain effective electrocatalysts for the process of lithium intercalation in graphite from organic aprotic electrolytes, occurring in lithium ion current sources. The processes of formation of the innercomplex compound of cobalt (III) with diethanolamine and the heteronuclear complex 2Co-Ni with diethanolamine have been investigated using IR spectroscopy and electronic spectra of absorption spectra in the UV and visible regions of the spectra. Summing up the study by the method of electronic absorption spectra, one can emphasize the presence in the process of formation of complex compounds of the bathochromic displacement of the maxima of d-d absorption bands of cobalt, which uniquely indicates the process of complex formation of the hetero-metallic compound. The composition of the coordination compounds obtained was determined using chemical analysis, whose results are well correlated with the theoretically calculated content of chemical elements. The probability of passage of complex formation reactions with the preservation of CoO4N2 cobalt coordination environment in the innercomplex complex compound of cobalt (III) and the polynuclear coordination compound [Ni(CoDetmHdetm)2](NO3)2, was confirmed, namely by the close assignment of characteristic-deformation-sensitive complexes fluctuations δas (CH) spectra chelate compounds of cobalt (III) and threenulear hetero-metallic complexes. The obtained results confirm the previous quantum-chemical calculations of the coordination node of the quadrgular 2Co-Ni complex with diethanolamine, which resulted in the assumption of the formation of four bridge connections of Co3+ ... O ... Ni2+ in the formation of a heterometal coordination compound [Ni(CoDetmHdetm)2](NO3)2.
