A thermally and hydrolytically stable microporous framework exhibiting single-chain magnetism: structure and properties of [Co2(H0.67bdt)3] x 20 H2O.

Fixing a hole: Hydrothermal chemistry has been exploited in the preparation of a 3D framework material exhibiting 48% accessible void volume and 1.5% hydrogen uptake by weight at 120 kPa (see picture). The title compound also exhibits single-chain magnetic behavior and reversible changes in magnetic properties upon solvation and desolvation.
