Reversible de-/resolvation and accompanied magnetism modulation in a framework of topologically ferrimagnetic [Co-3(mu(3)-OH)(2)](n) chains linked by a V-shaped ligand 4,4 '-dicarboxybiphenyl sulfone

A dynamic metal-organic framework consisting of topologically ferrimagnetic [Co-3(mu(3)-OH)(2)](n) chains connected by V-shaped 4,4'-dicarboxybiphenyl sulfone ligands, exhibits reversible de-/resolvation and accompanied magnetism modulation.
