The possibilities offered by hybrid materials formed by two molecular netwo
rks in the context of the molecular magnets are illustrated. Molecule-based
layered magnets are used as anionic hosts for electroactive molecules, wit
h the aim of obtaining multiproperty materials exhibiting in addition to th
e cooperative magnetism other interesting properties according to the natur
e of the inserted molecules. In particular, hybrid molecular compounds cont
aining molecular species giving rise to paramagnetic, conducting, or hi-sta
ble properties are reported.
