Synthesis and characterization of the first soluble phthalocyaninatorhenium complexes

The synthesis and characterization of the first soluble phthalocyaninatorhenium complexes with axial ligands nitride, N3− or oxide, O2− and ethoxide, EtO− soluble in common organic solvents are reported. Besides the monomer complexes (t-Bu)4PcReN (1) and (t-Bu)4PcReO(OEt) (3) a dimeric μ-oxo compound [(t-Bu)4PcReO]2O (4) was also prepared. The complexes were characterized by NMR, UV/Vis, IR, MS and CV. The nitrido complex is compared with the already known unsubstituted compound PcReN (2).
