文摘

Self-assembly through tuning the N-donor azole ligands and coordinative preferences of transition metal Cu(II), Cd(II) and Co(II) ions, three dimeric complexes, namely [Cu₂(Hmpz)₄(μ₂-Cl)₂Cl₂] (1), [Cd₂(pmtz)₂Cl₂(H₂O)₄] (2) and [Co₂(Hmptz)₂Cl₂(H₂O)₄]Cl₂·H₂O (3) have been synthesized at solvent method and hydrothermal conditions and characterized by single crystal X-ray diffraction analyses and fluorescent property were investigated, where Hmpz = 3-methyl-1H-pyrazole, Hpmtz = 5-methyl-1-phenyl-1H-1,2,3-triazole-4-carboxylic acid, and H₂mpta = 5-methyl-1-(1H-pyrazol-3-yl)-1H-1,2,3-triazole-4-carboxylic acid, respectively. In order to investigate the intermolecular contacts, Hirshfeld surface was studied in this work. The Hirshfeld surface analysis was successfully deployed here to visualize and elaborate the similarities and differences in the molecular environments of the three complexes.
