A novel 3,3′-(biphenyl-4,4′-diacyl)dipentane-2,4-dione-bridged di-nickel(Ⅱ) complex,[Ni_2(C_(22)H_(20)O_4)(C_(15)H_(11)O_2)_2]·3H_2O(C_(15)H_(11)O_2=1,3-diphenylpropane-1,3-dione anion;C_(22)H_(20)O_4=3,3′-(biphenyl-4,4′-diacyl)dipentane-2,4-dione dianion),was synthesized and characterized by the elemental analysis,conductivity,infrared spectra,electronic spectra and ESI-MS.Thermogravimetry(TG) and differential scanning calorimetry(DSC) for analyzing the compound in an atmosphere of N2 were performed.The magnetism of the di-nickel(Ⅱ) complex has been characterized with the aid of variable-temperature magnetic susceptibility (at 2～300 K).Moreover,it suggests that the coupling of Ni(Ⅱ)-Ni(Ⅱ) is ferromagnetic for the biphenyldiacetylacetone-bridged complex (with C=2.04 cm~3·mol~(-1)·K,and θ=8.10 K).
