脆性配位聚合物：五磷二茂铁[Cp*Fe（5-P5）]与弱配位阴离子[Al{OC（CF 3）3}4]-的AgI盐反应，以前所未有的1，2，3-配位模式产生包含环P5部分的聚合物（见图）。分析数据和DFT计算支持存在的单体/二聚体/低聚物在溶液中的平衡，这是完全有利于在室温下的单体和转移到二聚体/低聚物在降低的温度。
A fragile coordination polymer: The pentaphosphaferrocene [Cp*Fe(5-P5)] reacts with the AgI salt of the weakly coordinating anion [Al{OC(CF3)3}4]- to yield a polymer comprising cyclo-P5 moieties in an unprecedented 1,2,3-coordination mode (see figure). Analytical data and DFT calculations support the existence of a monomer/dimer/oligomer equilibrium in solution, which is entirely in favor of the monomer at room temperature and shifts to the dimer/oligomer at reduced temperatures.
