• Formation of mono- and binuclear chelates of alkyl-substituted biladiene-a,c with d-metal acetates in pyridine

  The complex formation reactions of several d-metal acetates with decamethyl-substituted biladiene-a,c (H2L) in pyridine (Py) have been studied by electronic spectroscopy. The coordination of H2L by zinc(II) and copper(II) affords mononuclear complexes [ML], and the coordination by cadmium(II) and mercury(II) produces binuclear heteroligand complexes [M2L(AcO)(2)], whereas the coordination by cobalt(II) gives binuclear biligand complexes [M2L2]. In a Py solution in the presence of a copper acetate excess, the ligand in the [CuL] complex is oxidized at the methylene spacer. The thermodynamic formation constants of the mono- and binuclear chelates have been determined from spectral data. The peculiarities of complex formation in pyridine and in dimethylformamide (DMF) are analyzed in comparison.

  The influence of the nature of a solvating medium on the chromophore properties and stability of alkyl-substituted biladiene-a,c dihydrobromide, a synthetic analogue of a bile pigment bilirubin, was analyzed. The results of the spectophotometric study of the protonation of a tetrapyrrol ligand and of the complex formation with Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II) acetates in DMF at 298.15 K were considered. Depending on the nature of a complex-forming cation and concentrations of reagents in solution the formation of complexes of three various types is possible: porphyrin-like (1 : 1), binuclear with different ligands (2: 1), and binuclear biligand (2: 2). The nature of metal cation renders essential influence on the formation of coordination polyhedra of the metal chelates with various structure.

  The reactions of protonated (H4L2+) and free (H2L) forms of the ligand 1,2,3,7,8,12,13,17,18,19-decamethylbiladien-a,c with zinc(II) acetate in dimethyl sulfoxide was studied by the spectrophotometric method. It was found that the mononuclear complex [ZnL] is formed in the studied systems. Constants of its formation were determined from the spectral data. Unlike H2L, the protonated [H4L2+] form has extremely low reactivity, because the initial stages of the complex formation mechanisms of the free and protonated forms of the ligand are different. Regularities of the solvent nature influence on the free energy of formation of biladien chelates were revealed.
