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.
已经制备了三种具有一维六边形通道的MOF-74型钴（II）框架。链中的钴（II）自旋通过羧酸盐和酚盐桥进行铁磁耦合。通过芳环路径的链间反铁磁耦合在钴-钴长度小于约10.9 Å时起作用，导致场诱导的变磁转变，而在长度大于约14.7 Å时不存在。
