当N，N '-双（4-吡啶基）脲与高氯酸锌反应时，其位置异构体N，N'-双（3-吡啶基）脲形成5重互穿的类金刚石网络，而其位置异构体N，N '-双（3-吡啶基）脲则形成网状氢键（4，4）网络（正方形网格网络），显示出温度依赖性的阴离子诱导的可逆单晶-单晶无序-有序相变。
While N,N'-bis(4-pyridyl)urea affords a 5-fold interpenetrated diamondoid network, its positional isomer N,N'-bis(3-pyridyl)urea gave a net-to-net hydrogen-bonded (4,4) net (square grid network) displaying temperature-dependent anion-induced reversible single-crystal-to-single-crystal disorder-order phase transition, when the ligands are reacted with zinc perchlorate.
