摘要: Solvated yttrium iodide precursors [Y(L)8]I3 [L = dimethylformamide (DMF) or dimethylsulfoxide (DMSO)], prepared in situ by stirring YI3(PriOH)4 DMF/DMSO, react with 3 equiv of PbI2 the presence NH4I to give novel hybrid derivatives based on either a one-dimensional (1D) straight chain, [Y(DMF)8][Pb3(μ-I)9]1∞·DMF (1), discrete pentanuclear iodoplumbates, [Y(DMSO)8]2[(DMSO)2Pb5(μ3-I)2(μ-I)8I6] (2a). The complex 2a and closely related [Y(DMSO)8][Y(DMSO)7(DMF)][(DMSO)2Pb5(μ3-I)2(μ-I)8I6] (2b) were obtained good yield solution phase transformation 1 DMSO under slight different conditions. Derivatives 2 also undergo unique solid-state confined environment paratone 1D polymers zigzag iodoplumbate chains; crystals transform into [Y(DMF)6(H2O)2][Pb3(μ3-I)(μ-I)7I]1∞ (3) via an exchange reaction, whereas those 2b are converted [Y(DMSO)7][Pb3(μ3-I)(μ-I)7I]1∞ (4) decomposition pathway. trifurcate H-bonding between wa...
