Two new d10 metal coordination polymers (CPs), [Zn(L)NO3]n (1) and [Cd(L)I2]n (2) (L = 4-(3-Pyridyl)-2H-1,2,3-triazole), have been designed and synthesized from ZnII/CdII ions and the rigid L ligand. The CPs 1 and 2 have been structurally characterized by single-crystal X-ray diffraction analyses, elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD) and thermal gravimetric analyses (TGA). CP 1 exhibits a hcb (3,3)-connected 2D network with the point symbol (63) and further forms a supramolecular 3D structure via hydrogen bonds. CP 2 reveals a 1D straight chain constructed by units of [Cd(1)N2I4] and hydrogen bonding leads to the formation of supramolecular 3D system. In addition, time-dependent density functional theory calculations with B3LYP functional were performed on L, CPs 1 and 2 to rationalize their experimental absorption spectra. The luminescence properties of L, CPs 1 and 2 in solid-state and different solvents have been also investigated.

Paragraph 0024, (2017/01/02)
The invention relates to a method for preparing 4-aryl-NH-1,2,3-triazole by the aid of aldehyde and sodium bisulfite adduct. The method is characterized by comprising steps as follows: the aldehyde and sodium bisulfite adduct, a nitrocompound, sodium azide, a solvent and an additive react at the temperature of 60-150 DEG C for 1-10 h with a one-pot method, after the reaction ends, aftertreament is performed, and 4-aryl-NH-1,2,3-triazole can be prepared. The cheap and easy-to-obtain aldehyde and sodium bisulfite adduct, nitrocompound and sodium azide are taken as raw materials, and 4-aryl-NH-1,2,3-triazole compounds can be conveniently prepared from the three components. Compared with existing methods, the method has the advantages that the raw materials are low in cost and simple and easy to obtain, the operation is convenient, and the reaction efficiency is high.
