Abstract

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. Interchain antiferromagnetic couplings via aromatic ring pathways operate over a Co-Co length shorter than ?10.9 Å, resulting in a field-induced metamagnetic transition, while being absent over lengths longer than ?14.7 Å.
