MAYER, Peter; YUMATA, Nonzaliseko C.; GERBER, Thomas I.A.  y  ABRAHAMS, Abubak'r. The oxidation of rhenium(III) by dioxygen in the presence of tri- and tetradentate N,O-donor ligands. S.Afr.j.chem. (Online) [online]. 2010, vol.63, pp.40-44. ISSN 1996-840X.

The oxidation of trans-[ReCl₃(MeCN)(PPh₃)₂] by dioxygen in the presence of the potentially tridentate N₂O-donor ligand 2-[((2-pyridinylmethyl)amino)methyl]phenol (Hham) in ethanol led to the formation of the hydrogen-bonded oxorhenium(V) dimer [ReOCl₂(ham)]₂. With the potentially tetradentate N₂O₂-chelate N,N-bis(2-hydroxybenzyl)-aminomethylpyridine (H₂hap), the '4 + 1' complex [ReOCl(hap)] was isolated. Both compounds were characterized by ¹Ή NMR and infrared spectroscopy, and X-ray crystallography.

Palabras clave : Oxidation; oxorhenium(V); multidentate ligands; crystal structures.
