A unique magnesium-based 3D MOF with nanoscale cages and temperature dependent selective gas sorption properties

A porous Mg-based 3D metal-organic framework with unique nanoscale cages and two-fold interpenetrating pcu nets has been synthesized and characterized. It shows gas-uptake capacities for N(2), H(2), O(2) and CO(2) at low temperatures and selective adsorption of CO(2) over O(2) and N(2) at room temperature.
