Tetrathiorhenate(VI), ReS42–. Spectroelectrochemical characterization (UV–VIS–IR) of a small new d1 system and of its tetrakis(2,2′-bipyridine)diruthenium(II) complex (EPR)
Abstract
ReS42– is the first d1 tetrathiometallate persistent enough to be studied with respect to change transfer, ligand field and IR vibrational spectra via spectroelectrochemistry; an EPR spectrum could only be detected of its trinuclear derivative [(bpy)2Ru(µ-ReS4)Ru(bpy)2]2+(bpy = 2,2′-bipyridine) at 4 K.
