Trans-dichloro-tris([51trovacenyl) stannate(IV), electro- and magneto-communication across a Cl-Sn-Cl backbone

摘要

Reaction of [5]lithiotrovacene (TVC-Li) with tin dichloride affords the triradical complex (THF)_3Li~+[(TVC)_3SnCl_2]~- which was characterized by X-ray crystallography, cyclic voltamme-try, EPR spectroscopy and magnetic susceptometry; redox splittings δE_(1/2) ("electrocomnunication") and the exchange parameters J_(EPR) and J_χ ("magnetocommunication") attest to inter vanadium interactions mediated by the central tin atom.
