Trans-dichloro-tris([5]trovacenyl)stannate(iv), electro- and magneto-communication across a Cl-Sn-Cl backbone.

Reaction of [5]lithiotrovacene (TVC-Li) with tin dichloride affords the triradical complex (THF)(3)Li(+)[(TVC)(3)SnCl(2)](-) which was characterized by X-ray crystallography, cyclic voltammetry, EPR spectroscopy and magnetic susceptometry; redox splittings deltaE(1/2) ("electrocommunication") and the exchange parameters J(EPR) and J(chi) ("magnetocommunication") attest to inter vanadium interactions mediated by the central tin atom.
