single-stranded helical coil structures, which are controlled by the variation of the geometry around the coordination site in ligands. Moreover, the coordination of L(1)() and L(2)() to Mn(hfac)(2) (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate) yields single-stranded helical coordination polymers of [Mn(L(1)())(hfac)(2)]( infinity ) (5) and [Mn(L(2)())(hfac)(2)]( infinity ) (6), respectively.
研究了具有120度分子角和金属中心的刚性角配体的自组装,以实现配位聚合物结构的合理构造和改性。Co(NCS)(2)与1,3-双(反式-4-苯乙烯基吡啶基)苯(L(1)()),2,6-双(反式-4-苯乙烯基吡啶基)吡啶(L(2 )()),1,3-双(反式-4-苯乙烯基嘧啶基)苯(L(3)())和1,3-双(反式-4-苯乙烯基喹啉基)苯(L(4)())提供络合物[Co(L(1)())(2)(NCS)(2)](无穷大)(1),[Co(L(2)())(2)(NCS)(2)](无穷大)(2),Co(L(3)())(2)(NCS)(2)(CH(3)OH)(2)(3)和[Co(L(4)())(NCS )(2)](无穷大)(4)。生成的络合物具有开放骨架,阶梯状氢键链和单链螺旋线圈结构,它们受配体配位位点周围几何形状的变化控制。此外,L(1)()和L(2)()与Mn(hfac)(2)的配位(hfac = 1
