Abstract

The electronic structures of the [V(tbpy)3]z (z = 3+, 2+, 0, 1−) have been elucidated by magnetochemical, spectroscopic, and computational methods that show sequential reduction of the 4,4′-di-tert-butyl-2,2′-bipyrdine (tbpy) ligands with retention of a central V(II) ion for z = 2+, 1+, 0, 1−. The ambiguously assigned oxidation state of the V ion in the neutral species is now correctly diagnosed by V K-edge X-ray absorption spectroscopy, and the net metal-centered S = 1/2 ground state arises from from strong antiferromagnetic coupling of two bpy π-radicals with the d3 V(II) ion.
