摘　　要：在水热条件下,将铜金属配合物插入到铀酰有机框架化合物中,合成了两例新型铀/铜异金属杂化配合物[Cu(bipy)(UO_(2))(bdc)_(2)·H_(2)O]_(n)(1),{[Cu(phen)(UO_(2))(bdc)(bc)(H_(2)O)]·H_(2)O}_(n)(2)(bipy=2,2′-联吡啶,bdc=对苯二甲酸,phen=1,10-邻菲罗琳,bc=苯甲酸),并通过X射线单晶衍射对其结构进行了表征。配合物1属于单斜晶系,P2_(1)/c空间群,M_(r)=833.99,a=7.9077(5)A,b=23.1076(13)A,c=14.6172(8)A,β=101.4180(10)°,V=2618.1(3)A^(3),Z=4,D_(c)=2.116 g·cm-3,μ=7.056 mm^(-1),F(000)=3003,最终偏离因子R=0.0210,wR=0.0560。配合物2属于单斜晶系,P2/c空间群,Mr=829.99,a=7.9327(2)A,b=11.6546(3)A,c=13.8618(4)A,β=96.2230(10)°,V=1274.01(6)A^(3),Z=2,Dc=2.164 g·cm^(-3),μ=7.247 mm^(-1),F(000)=786,最终偏离因子R=0.0273,wR=0.0749。在对苯二甲酸配体桥联下这两个配合物都具有三维异金属网络结构(CCDC:860177,1;CCDC:857137,2)。此外,测试了配合物1和2的固态紫外-可见吸收光谱并研究了配合物1的固态荧光性能。By incorporating Cu complex into uranyl-organic framework,two new U/Cu heterometallic complexes,[Cu(bipy)(UO_(2))(bdc)_(2)·H_(2)O]_(n)(1),{[Cu(phen)(UO_(2))(bdc)(bc)(H_(2)O)]·H_(2)O}_(n)(2)(bipy=2,2′-bipy,bdc=benzene-1,4-dicarboxylate acid,phen=1,10-phenanthroline,bc=benzoic acid),were synthesized under hydrothermal conditions and structurally characterized by X-ray single-crystal diffraction.Crystal data for 1:monoclinic system,space group P2_(1)/c with Mr=833.99,a=7.9077(5)A,b=23.1076(13)A,c=14.6172(8)A,β=101.4180(10)°,V=2618.1(3)A^(3),Z=4,D_(c)=2.116 g·cm^(-3),μ=7.056 mm^(-1),F(000)=3003,the final R=0.0210 and wR=0.0560 for 5382 reflections I>2σ(I).Crystal data for 2:monoclinic system,space group P2/c with Mr=829.99,a=7.9327(2)A,b=11.6546(3)A,c=13.8618(4)A,β=96.2230(10)°,V=1274.01(6)A^(3),Z=2,Dc=2.164 g·cm-3,μ=7.247 mm^(-1),F(000)=786,the final R=0.0273 and wR=0.0749 for 2172 reflections I>2σ(I).The two complexes exhibit 3-D heterometallic network based on bridged bdc ligand(CCDC:860177,1 and CCDC:857137,2).In addition,the UV-Vis diffuse-reflectance spectra of 1 and 2 were measured at room temperature and the solid luminescent property of 1 was studied at room temperature.
