Abstract
The thermodynamics and kinetics of the formation of coordination compounds of cobalt(III) 5,15-di-(ortho-nitrophenyl)-2,8,12,18-tetramethyl-3,7,13,17-tetrabutylporphyrinate with nitrogen organic bases in an inert solvent were studied. The type of the structure was determined, the stability and the degree of deformation of the molecular complex were estimated. The dependence of the coordination properties of the cobalt(III) 5,15-di(ortho-nitrophenyl)-2,8,12,18-tetramethyl-3,7,13,17-tetrabutylporphyrinate on the electronic and conformational factors of the macrocycle was revealed. The geometry of the cobalt porphyrinate molecule and its molecular complexes was optimized by the PM3 method, the presence of steric strain in these molecules was found, and the binding energy of the metal atom to the N-base was calculated. A good agreement between the calculated and experimental data was demonstrated.
