Coordination Polymer Nanobamboos of {FexIn1-x}- MIL-88B: Induced Formation of a Virtual In- MIL-88B

A precise fabrication of nanobamboo structures made from hybrid coordination polymers of the type {FexIn1-x}-MIL-88B is demonstrated. The compositions of the hybrid coordination polymer nanobamboos of {FexIn1-x}-MIL-88B (x=0.06, 0.19, or 0.75) are regulated by altering the amount of metal ions used in the reactions. Interestingly, the formation of a virtual In-MIL-88B (precise structure, {Fe0.06In0.94}-MIL-88B), which cannot be created in a typical reaction, is induced by the assistance of a Fe-MIL-88B structure. The a and c cell parameters of {Fe0.06In0.94}-MIL-88B are calculated at 10.95 and 19.86 angstrom, respectively. These values of {Fe0.06In0.94}-MIL-88B are larger than those of pure Fe-MIL-88B owing to the large ionic size of In3+ within the framework.
