Abstract

Reaction of [ReO2(PPh3)2I] and [ReNCl2(PPh3)2] with 2,2′:6′,2″:6″,2‴-quaterpyridine (L) in methanol gave [ReO(L)(OMe)2]ClO4and [ReN(L)(PPh3)Cl]ClO4respectively. The structures determined by X-ray crystallography revealed seven-co-ordination around rhenium with Re=O and Re=N distances of 1.666(4) and 1.647(6) Å respectively. Intense metal-to-ligand charge-transfer transitions in the visible region and reversible ReVI-ReVredox couples have been observed for both complexes in acetonitrile.
