(Phthalocyaninato)ruthenium(II) (PcRu) reacts with different azanaphthalenes such as quinoxaline, 2-methylquinoxaline, quinazoline, phthalazine, quinoline, pyrido [2,3-b]pyrazine, cussed in detail for all the complexes prepared. pteridine, isoquinoline and 1,5-naphthyridine to form the corresponding bisaxially coordinated PcRuL, complexes 1 -9. The IR, 'H-NMR, UV/Vis, TG/DTA, and FD-MS data are disBisaxially coordinated macrocyclic transition-metal complexes MacMLz and bridged systems [MacM(L)], with phthalocyanine (Pc), tetrabenzoporphyrin (TBP), or 1,2-and 2,3-naphthalocyanine (1,2-, 2,3-Nc) as the macrocycle (Mac), transition metals, e.g. iron, ruthenium, and cobalt as the central metal atom (M), and ligands (L) like pyrazine (pyz), tetrazine (tz), diisocyanobenzene (dib), etc. have been systematically investigated by us regarding their semiconducting properties','). The semiconducting behavior of the bridged systems [MacM(L)], as well as other properties, e.g. solubility of the monomers MacMLt in organic solvents, do not only depend on the macrocycle Mac, but also on the nature of the ligands L3).For the synthesis of bisaxially coordinated transitionmetal complexes MacMLz and [MacM(L)], till now only monocyclic ligands of the type mentioned above have been used. It is expected, that structually different ligands containing a more extended x system, could lead to different physical properties of the corresponding complexes, e.g. to higher solubilities in organic solvents or to lower oxidation potentials.In this report, we describe for the first time the synthesis and properties of the azanaphthalene-coordinated (phthalocyaninato)ruthenium(II) complexes 1 -9.
