The results of MWG calculations of the electronic structures of real Co(III) complexes [Co(HD)₂L¹L²]ⁿ were used to analyze the electron density distribution and to determine the charges on atoms and configurations, where n is the charge of the complex and HD is the acid residue of dimethylglyoxime (H₂D); L¹ = NH₃ at L² = NH₃, Cl^-, Br^-, or I^- and L¹ = L² = Cl^- and L¹ = H₂O or NO₂^- at L² = NO₂^-, with self-consistency over all atoms of the system and over d, s, and p configurations of cobalt. The mutual influence of the ligands (trans- and cis-) was shown to be determined by the atomic charges and bond orders on the axial coordinate and in the equatorial plane of the complex. The following order of the trans-effect was proposed: I^- > Br^- > Cl^- > NO₂^- > NH₃ > H₂O. The effects of the electronic factors on distorsion and conformational processes in the complexes were discussed
