Synthesis and crystal structure of an oxorhenium(V) complex containing a tridentate imidazole ligand

Abstract

The reaction of equimolar amounts of (n-Bu₄N)[ReOCl₄] and 2-(1-ethanolthiomethyl)-1-methylimidazole (Htmi) in acetonitrile yielded cis-[ReOCl₂(tmi)]. An X-ray diffraction study shows that tmiˉ coordinates as a uninegative N,S,O-tridentate ligand to give distorted octahedral geometry around the rhenium(V) ion. The three donor atoms occupy a triangular face in an octahedron, with the alcoholate oxygen coordinated trans to the oxo group. 

KEY WORDS: Oxorhenium(V), N,S,O-tridentate, Imidazole
