| 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.
