5-取代-1-氢四唑合成中捕获的一个新奇的三维镉配聚物(英文)

An Unexpected Intermediate or Precipitate——Novel 3D Cd-Coordination Polymer Formed in the Preparation of 5-Substituted 1H-Tetrazoles from Nitrile in Water

在水热条件下,1,4-对二氰基苯,氯化镉以及叠氮化纳反应,成功地组装了一个三维网状镉四唑配位聚合物[monoaqua-4-tetrazolyl-benzenecarboxylate cadmium(Ⅱ)(1)],该化合物并不是预期的双四唑镉配位聚合物,而是其中一个氰基水解成羧基形成了单四唑镉配位聚合物。晶体结构分析表明,化合物1具有PtS的拓扑结构,室温下,化合物1显示强的蓝色荧光。

The hydrothermal reaction of 1,4-dicyanobenzene with NaN3 in the presence of (HO)-O-2 and Lewis acid (CdCl2) unexpectedly affords a novel mono-tetrazole Cd coordination polymer, monoaqua-4-tetrazolyl-benzene carboxylate cadmium(II) (Te-Ph-CA)Cd(H2O) (1), rather than an expected Sharpless's precipitate product with bis(tetrazolyl)benzene ligand. 3D Network of 1 with a PIS topology highlights the importance in construction novel supramolecular motifs through in situ ligand-synthesis. Its strong blue fluorescent property is also reported.
