摘　　要：用硝酸镉与1-萘甲酸、邻菲罗啉水热合成了配合物[Cd(na)_2(phen)_2]·[Cd(na)_2(phen)_2]·3H_2O(Hna=1-萘甲酸,phen=1,10-邻菲罗啉),并用X-射线单晶衍射、红外、热重和元素分析进行了结构表征。结果表明,该配合物属三斜晶系,P-1空间群,晶胞参数为:a=1.27123(16)nm,b=1.6369(4)nm,c=1.9656(2)nm,α=75.613(2)°,β=84.363(2)°,γ=71.5380(10)°,Z=2,V=3.7572(8)nm^3。配合物包含两个离散的单核[Cd(na)_2(phen)_2]子单元和三个结晶水分子,并通过分子间氢键形成三维超分子结构。在335 nm的紫外光激发下,配合物发射出源于Na-之间电子跃迁的荧光。A cadmium（ II） complex [Cd（ na）_2（ phen）_2]·[Cd（ na）_2（ phen）_2]·3H_2O（ Hna = 1-naphthoate,phen = 1,10-phenanthroline） has been hydrothermally synthesized by reacting cadmium nitrate with 1-naphthoate acid and phen at hydrothermal condition. The complex was structurally characterized by single crystal X-ray diffraction,elemental analyses,IR and TGA,and the solid-state fluorescent spectrum was investigated. X-ray diffraction analysis of single crystal shows that the complex is crystallized in triclinic crystal system and P-1 space group. The cell parameters are as follows a = 1.27123（ 16） nm,b = 1. 6369（ 4） nm,c = 1. 9656（ 2） nm,α = 75. 613（ 2） °,β = 84. 363（ 2） °,γ = 71.5380（ 10） °,Z = 2,V = 3. 7572（ 8） nm-3. The asymmetric unit consists of two independent [Cd（ na）_2（ phen）_2]units and three water molecules,and the complex is linked to 3D supramolecular architecture by abundant and interesting intermolecular C-H ···O hydrogen bonding. Furthermore,the complex exhibits strong fluorescent emissions resulting from na--based intraligand charge transfer at room temperature under 335 nm excitation.
