以9,10-蒽-3,3'-双(1,3-戊二烯-2,4-二醇)和二苯甲酰甲烷为原料合成了新型固态三元配合物[Ni_2(C_(24)H_(20)O_4)(C_(15)H_(11)O_2)_2]-H_2O,并用元素分析、电导率、红外光谱、电子光谱和电喷雾质谱对其进行了表征,确定了配合物的组成,研究了配合物在氮气气氛中的热分解行为.其荧光光谱的最大发射波长为430 nm,变温磁化率(2-300 K)的测定结果表明桥联双核Ni~(2+)配合物为铁磁性自旋交换作用,Curie常数C=2.04 cm~3·mol~(-1)·K,Weiss常数0=8.10 K.
A novel 3,3'-(anthracene-9,10-diyl)dipentane-2,4-dione-bridged di-nickel(Ⅱ)complex,[Ni_2(C_(24)H_(20)O_4(C_(15)H_(11)O_2)_2]·H_2O(C_(15)H_(11)O_2=1,3-diphenylpropane-1,3-dione anion;C_(24)H_(20)O_4=3,3'-(anthracene-9,10-diyl)dipentane-2,4-dione dianion),was synthesized and characterized by the element analysis,conductivity,infrared spectra.electronic spectra and ESI-MS.Thermogravimetry(TG)and differential scanning calorimetry (DSC)for the compound in an atmosphere of N2 was performed.It exhibited one intense fluorescent emission band at 430 nm.The magnetism of the di-nickel(Ⅱ)complex was characterized with the aid of variable-temperature magnetic susceptibility(2～300 K).Moreover,it suggested that the coupling of Ni(Ⅱ)-Ni(Ⅱ)was ferromagnetic for the binuclear-bridged complex(C=2.04cm_3·mol_(-1)·K,θ=8.10K).
