reacted with a Cu(II) salt resulting in the formation of a metallosupramolecular cage [Cu2(μ-L1)4(DMSO)2(H2O)2}·SO4·X] (1) and a one-dimensional coordination polymer [Cu(1)(μ-L2)2(H2O)2}Cu(2)(μ-L2)2(H2O)2}·2SO4·9H2O·X]n (2) (where DMSO = dimethylsulfoxide, and X = disordered lattice included solvent molecules), respectively. The single crystal structures of 1 and 2 are discussed in the context of the
两个双吡啶基-双脲配体,即N,N'-双-(3-吡啶基)二苯基亚甲基-双脲(L1)和N,N'-双-(3-吡啶基)二苯基亚甲基-双脲(L2)已与Cu(II)盐反应,形成了金属超分子笼[Cu 2(μ- L1)4(DMSO)2(H 2 O)2 }·SO 4 ·X](1)和一维配位聚合物[Cu(1)(μ- L2)2(H 2 O)2} Cu(2)(μ- L2)2(H 2 O)2 }·2SO 4 ·9H 2 O·X] n(2)(其中DMSO =二甲基亚砜,X =包含溶剂分子的无序晶格) 。在配体特别是配体的氢键官能度对在这些金属有机化合物中观察到的超分子结构多样性的影响的背景下讨论了1和2的单晶结构。的超分子填料1显然是由溶剂的性质的影响和配体所使用; DMSO / MeOH或DMSO / H 2的混合物O分别导致形成蓝色晶体或水凝胶。
