Control of Interchain Antiferromagnetic Coupling in Porous Co(II)-Based Metal-Organic Frameworks by Tuning the Aromatic Linker Length: How Far Does Magnetic Interaction Propagate?
Three MOF-74-type Co(II) frameworks with one-dimensional hexagonal channels have been prepared. Co(II) spins in a chain are ferromagnetically coupled through carboxylate and phenoxide bridges. Interchairi antiferromagnetic couplings via aromatic ring pathways operate over a Co-Co length Shorter than similar to 10.9 angstrom, resulting in, a field-induced metamagnetic transition, while being absent over lengths longer than similar to 14.7 angstrom.
