Pillar substitution in a long-known metal–organic material with saturated metal centres, [Cu(bipy)2(SiF6)]n, has afforded the first crystallographically characterized porous materials based upon TiF62− and SnF62− anions as pillars. Gas adsorption studies revealed similar surface areas and adsorption isotherms but enhanced selectivity towards CO2vs. CH4 and N2.
