Paramagnetic and diamagmetic [Z III Cp] + organometallic complexes were used as “templating” cations to prepare a series of hybrid layered magnets based on bimetallic oxalate complexes (see figure). These salts show spontaneous magnetization below T c , corresponding to the presence of ferro‐, ferri‐, or canted antiferromagnetism. The effects of the paramagnetic and ferromagnetic sublattices on the magnetic properties of these compounds were studied by magnetic measurements, and by ESR and Mössbauer spectroscopy.
