Reaction of two tripodal ligands, 2,4,6-tris(4-((2-methyl-benzimidazol-1-yl)methyl)phenyl)-1,3,5-triazine (L111) and 1,3,5-tris(4-((2-methyl-benzimidazol-1-yl)methyl)phenyl)benzene (L222), with AgSbF6 led to formation of two types (6,3) networks in one single crystal, of which one is three-fold Borromean topologically entangled while the other is independent, showing the same chirality and sandwiched Borromean stacking.
2,4,6-三(4-((2-甲基-苯并咪唑-1-基)甲基)苯基)-1,3,5-三嗪(L111)和 1,3,5-三(4-((2-甲基-苯并咪唑-1-基)甲基)苯基)苯(L222)这两种三元配体与 AgSbF6 反应后,在一个单晶体中形成了两种类型的 (6,3) 网络,其中一种网络在拓扑学上是三折硼罗米纠缠网络,而另一种网络则是独立网络、在 AgSbF6 的作用下,在一个单晶体中形成了两种(6,3)网络,其中一种是三折博罗梅拓扑纠缠网络,而另一种是独立网络,显示出相同的手性和夹层博罗梅堆叠。
