Ferromagnetic interactions between triphenylmethyl radicals through an organometallic coupler

A diradical consisting of two polychlorinated triphenylmethyl radical units connected by a 1,1′-metallocenylendivinylene bridge has been synthesized and characterized; EPR frozen solution experiments down to liquid helium temperature showed that the organometallic unit acts as a ferromagnetic coupler.
