摘要
A new complex [Co（4,4＇-bpy）2（H2O）2（4-FBA）2]·（4,4＇-bpy）（1） has been hydro-thermally synthesized using cobalt,4,4＇-bipyridyl（4,4＇-bpy） and 4-fluorobenzoic acid（4-HFBA）,and characterized by thermal analysis,single-crystal X-ray diffraction and magnetic property.The complex crystallizes in the triclinic system,space group P,Z = 1.Crystal data：C54H44CoF2N8O6,Mr = 997.90,a = 9.134（2）,b = 11.555（2）,c = 12.867（3） ,α = 66.02（3）,β = 77.96（3）,= 73.11（3）°,V = 1180.9（4） 3,Dc = 1.403 g/cm3,μ（MoKα） = 0.433 mm-1,F（000） = 517,the final R = 0.0633 and wR = 0.1171 for 2152 observed reflections（I 〉 2σ（I））.The title complex is assembled into 1D supramolecular chains parallel to [001] based on the adjacent molecular ··· stacking interactions and hydrogen bonds.The variable temperature magnetic measurements show a weak ferromagnetic behavior over 300-160 K followed by antiferromagnetic behavior below 160 K for the title complex.
