A Three-Dimensional Metal-Organic Framework with an Unprecedented Octahedral Building Unit

摘要

Among the numerous works devoted to porous hybrid solids,those on structures built up from a chosen inorganic unit reticulated with rigid organic linkers are very topical.The major goal is to control the "design" of the architectures to obtain materials with required properties.Interesting architectures have been obtained with tetrameric ZnO_4 units,cuboid zinc silicate cores,and triangular oxo-centered building units with vanadium,zinc,and iron.Recently,a crystalline metal-organic framework(MOF),MIL-100,with a giant cell and a large sorption capacity(3100 m~2g~(-1))was constructed from this type of triangular unit containing chromium and trimesate ions.
