•Homo-dimetal phthalocyanines MPc(OR)6-MPc(OR)6 (M = Co, Ni) (1, 2) were synthesized.•Complexes 1 and 2 are evidenced by the mass and NMR spectroscopic characterization.•Compound 1 has been characterized by single crystal X-ray diffraction analysis.
Reaction of metal free homobinuclear phthalocyanine H2Pc(OR)6-H2Pc(OR)6 with M(OAc)2 (M = Co, Ni) in refluxing dimethyl formamide led to the isolation of the binuclear phthalocyaninato metal complexes MPc(OR)6-MPc(OR)6 (M = Co, Ni) (1, 2). These binuclear phthalocyanine compounds were characterized by a series of spectroscopic methods including mass, 1H NMR, electronic absorption, and IR spectroscopy in addition to elemental analysis. In particular, their binuclear phthalocyanine nature has been directly revealed on the basis of single crystal X-ray diffraction analysis of the homo-dicobalt species CoPc(OR)6-CoPc(OR)6 (1) for the first time. In addition, their electrochemical data over these binuclear phthalocyanine compounds have also been provided by cyclic voltammetry measurements.
