Single-molecule magnetism arising from cobalt(II) nodes of a crystalline sponge

The remarkable Metal-Organic Framework (MOF), {[(Co(NCS)(2))(3)(kappa(3)-TPT)(4)]center dot a(H2O)center dot b(MeOH)}(n) (1), which is used in the revolutionary crystalline sponge method, displays characteristic Single-Molecule Magnet (SMM) behaviour under applied static fields. We report the subtle...
