摘要：

Spectroscopic and computational examination of the neutral tris-dioxolene complex [V(dbcat)(3)] (dbcat(2-) = 3,6-di-tert-butylcatecholate) reveals a Class III mixed-valent ground state. The radical is stabilised by delocalisation across the ligands mediated by the energy matched d orbital manifold of the V(v) centre. This electronic structure is compared to the tris-dithiolene and tris-diimine analogues that possess V(iv) and V(ii) ions, respectively.
