A rational synthetic route leading to 3d–3d′–4f heterospin systems: self-assembly processes involving heterobinuclear 3d–4f complexes and hexacyanometallates

Abstract

A novel heterospin system, [{CuL}Gd(H2O)3{Fe(CN)6}]·4H2O, is obtained by reacting the mononuclear complex, [CuL], with gadolinium(III) nitrate, followed by the substitution of the nitrato groups with [Fe(CN)6]3− ions (L2− = N,N′-propylenedi(3-methoxysalicylideneiminato)).
