were studied in this work using various ligand modifications and Ag(I) salts. In particular, six new ligand classes were prepared with the following features: (1) The steric hindrance on the pyrazole rings L3,3′Me, L5,5′Me, L5,3′Me, LCF3, and LBr was modified. (2) The steric hindrance was reduced on the peripheral thioether group: LSMe. (3) Finally, the presence of fluorine and bromine atoms in LCF3
这项工作检查了15种Ag(I)与硫醚官能化的双(吡唑基)甲烷衍生物的配合物的晶体结构,以合理化配体对(a)配位聚合物(CP),(b)寡核(六聚和双核)形成的影响。 )复合物,以及(c)单核复合物。先前已经报道了这种配体类别如何产生具有永久孔隙的微孔结构。一些配体修饰可以在保持相同总体结构的同时诱导腔尺寸调节。双(吡唑基)甲烷支架可以很容易地用各种结构片段官能化。因此,在这项工作中使用各种配体修饰和Ag(I)盐研究了结构结果。特别地,制备了具有以下特征的六种新的配体类别:修饰了3,3'Me,L 5,5'Me,L 5,3'Me,L CF3和L Br。(2)在周围的硫醚基:LSMe上,位阻降低。(3)最后,L CF3和L Br中氟和溴原子的存在提供了扩大相对于基于烃取代基(CH 3,苯基,萘基)的配体的相互作用类型的可能性。使用不同的Ag(I)前驱体(例如AgPF 6,AgBF 4,AgCF 3
