Hybrid molecular materials based on organic molecules and the inorganic magnetic cluster [M₄(H₂O)₂(PW₉O₃₄)₂]^10–(M²⁺=Co, Mn)

Abstract

The synthesis and physical characterization of new organic–inorganic hybrids formed by conducting and magnetic networks are reported. The crystalline radical salts are formed by BEDT-TTF type donors as the organic part, and by large metal–oxide clusters of the type [M₄(H₂O)₂(PW₉O₃₄)₂ ]^10– (M²⁺=Co, Mn) as the inorganic part. We also show how these magnetic clusters can be incorporated in conducting organic polymers to give hybrid organic–inorganic films.
