A bimetallic pillared-layer metal-organic coordination framework with a 3D biporous structure

A novel bimetallic [Mn(II)-Fe(III)] 3D biporous pillared-layer metal-organic coordination framework constructed by a cyanometallate anion ([Fe(CN)(6)](3-)) and an organic linker (4,4'-bipy) is found to exhibit permanent porosity with excellent size selective vapour sorption properties and H-2-storage capability.
