Surface‐modified Fe 3 O 4 nanoparticles (NPs) can be obtained by substituting [(η 5 ‐semiquinone)Mn(CO) 3 ] for oleylamine surface protecting groups. The resulting NP can function as a nucleus or template to generate crystalline coordination polymers that contain superparamagnetic Fe 3 O 4 NPs. Hybridized magnetic properties can be obtained by introducing paramagnetic metal nodes, such as Mn 2+ , into the polymers (see picture).
