两个镧系配合物的合成, 晶体结构及荧光性质

合成了两个新配合物, Eu2(Pht)2(HPht)2(Phen)2(H2O)4] (1) and Gd(3-CNC6H4COO)3(H2O)2]n (2) (Pht2―=dianion of o-phthalic acid; HPht―=mono-anion of o-phthalic acid; Phen=1, 10-phenanthroline; 3-CNC6H4COO=3-cyanobenzoate), 并通过X-射线单晶衍射表征其结构。结果表明，在水热反应条件下1，3-苯二腈水解为3-氰基苯甲酸。配合物2形成了一维链状配合物，而配合物1形成了二聚体。配合物1属三斜晶系，空间群 ，晶胞参数为a = 1.01048(6) nm, b = 1.06755(7) nm, c = 1.19266(8) nm, α = 90.188(3)º, β = 99.526(2)º, γ = 100.981(2)º, V = 1.24479(14) nm3, Z = 1, Dc = 1.861 Mg/m3；配合物2也属三斜晶系，空间群 ，晶胞参数为a = 0.93749(9) nm, b = 1.14943(10) nm, c = 1.27024(11) nm, α = 90.188(3)º, β = 73.788(5)º, γ = 86.757(5)º, V = 1.19389(19) nm3, Z = 2, Dc = 1.757 Mg/m3。用激发和发射光谱研究了配合物1的荧光性质，该化合物能发射很强的红色荧光。
