Cooperation between metal and ligand in oxygen atom transport by N-confused porphyrin oxorhenium(V) complexes.

N-Confused porphyrin oxorhenium(V) complexes were prepared and their X-ray structures were elucidated. The oxorhenium(V) complexes can transfer oxygen atom from pyridine N-oxide to triphenylphosphine, in which unique cooperation between metal and ligand was observed.
