两个具有二维44菱形网格和三维64·82压缩NbO骨架的超分子异构体：α-[Cd（SH）2（S-bztpy）]·2 H2O（1）和β-[Cd（SH）2（E-bztpy）]·2 H2O（2）（bztpy = 1，2，4，5-四（4-吡啶基）苯），已经在一锅反应中合成，包括溶剂热原位配体产生和BZTPY配体的构象异构体分离。结构拓扑的变化是由于bztpy配体通过吡啶和苯环之间的C-C键的旋转而产生的构象自由，这赋予它们有趣的不同发光性质。
Two supramolecular isomers with two-dimensional 44 rhombic-grid and three-dimensional 64·82 compressed-NbO frameworks, α-[Cd(SH)2(S-bztpy)]·2H2O (1) and β-[Cd(SH)2(E-bztpy)]·2H2O (2) (bztpy = 1,2,4,5-tetra(4-pyridyl)benzene), have been synthesized in a one-pot reaction, involving solvothermal in situ ligand generation and conformational isomers separation of the bztpy ligand. The variation in structural topology results from the conformational freedom of the bztpy ligand through rotation of the C—C bonds between pyridine and benzene rings, which imparts them with intriguingly different luminescence properties.
