Synthesis and Characterization of a Family of Molecule-Based Ferrimagnetic Network Solids Containing Fluoro-Substituted Dicyanostilbene Acceptors

Abstract

Three new coordination network molecule-based ferrimagnets of the general formula [V(acceptor)2]·x(solvent), where acceptor = 3,3′,5,5′-tetrafluorodicyanostilbene, 3,3′,4,4′,5,5′-hexafluorodicyanostilbene, or 2,2′,3,3′,5,5′,6,6′-octafluorodicyanostilbene and V = vanadium(II), have been prepared with ordering temperatures between 150 and 190 K. Including a previously reported compound, V[DCPFS]2·x(solvent), where DCPFS = dicyanoperfluorostilbene, the four represent a family of closely related compounds whose ordering temperatures can be used to infer the effects of fluorine substitution on the acceptors.
