Based on the ligand 3-（2-pyridyl）-5-（3-pyridyl）-1-H-1,2,4-triazole（2,3′-Hbpt）,a new coordination compound[Co2（2,3′-bpt）4]was constructed by hydrothermal reation.The title complex was characterized by single crystal X-ray diffraction analysis,infrared spectrum,and elemental analyses.Compound 1crystallizes in the triclinic system,space group P-1,the 2Dstructure of complex 1was constructed due to 2,3′-Hbpt in momodentate and bidentate fashion.In addition,thermostability of complex 1was investigated by TG.Theoretical calculation based on density functional theory at B3lyp/6-31G＊＊level was also employed to explicate the optimal configuration and the coordination mode of 2,3′-Hbpt.Notably,the geometry and conformation of the ligand in complex 1are in accordance with the calculated results.
