Abstract

The present report describes two series of new porphyrazine macrocycles derived from tetrakis(selenodiazole)porphyrazine, TSeDPzH₂, having the formulae [TSeDPzM](CH₃COOH)(H₂O)_xM = Mn(II), Co(II), Ni(II), Zn(II); x = 4–6) and [TSeDPzM(py)](CH₃COOH)(H₂O)_x (M = Mn(II), Co(II), Ni(II); x = 1–5), obtained by reaction of the free ligand with the appropriate metal acetate in dimethyl (DMSO), and, respectively, pyridine. All the species isolated are stable-to-air substantially amorphous materials, almost completely insoluble in the usual organic solvents and N-donors (pyridine etc.), and only slightly soluble in CF₃COOH or 96% H₂SO₄. The complexes have been investigated by IR, Raman, and UV-vis spectra, and magnetic susceptibility measurements. Their properties in terms of electronic structure and reactivity towards N-bases are discussed in comparison with their S-containing analogs and the class of the structurally similar metal phthalocyanines.
