The reactions of symmetric and nonsymmetric alkyl-substituted 2,2'-dipyrrolylmethenes with Cu(II), Ni(II), Co(II), Zn(II), Cd(II), and Hg(II) acetates in dimethylformamide solutions at 298.15 K were studied. The formation of hetero- and homoligand complexes was observed in the systems studied depending on the concentration conditions and the nature of the complexing metal. The stepped and complete constants of formation for metal complexes were determined. The key trends of the influence of the metal and ligand nature on the stabilization of the complexes were established.
