| Abstract: Two transition-metal complexes, [Zn(suc)(HL)]n (1) and [Cd(suc)0.5(L)]n (2) (H2suc=succinic acid, HL=3-(2-pyridyl)pyrazole), have been achieved under hydrothermal conditions and structurally characterized by elemental analysis, IR spectrum, single-crystal X-ray diffraction, thermogravimetric analysis, fluorescent spectroscopy, and powder X-ray diffraction. In complex 1, the carboxyl ligand suc2- bridges the metal centers via bidentate and monodentate modes. The metal centers are coordinated by suc2- to form a 2D network structure. In 2, suc2- and L-ligands linked the Cd (Ⅱ) ions to form a 2D framework too. Besides, the quantum-chemical calculations were finished on ‘molecular fragments’selected from the crystal structure of 1 and 2 by the PBE0/LANL2DZ method in the Gaussian16 program. The calculation results indicate the distinct covalent interaction between the coordinated atoms and Zn(Ⅱ) ion/Cd(Ⅱ) ion. |
