摘要
以1,10-邻菲罗啉(phen)为配体,采用溶剂蒸发法在水中分别合成了羟基桥连和氯离子桥连的两个新型的含氮配体多核铜离子配合物[Cu4(phen)4(H2O)2(OH)4·(NO3)4·2H2O(1)和Cu2(phen)2Cl4(2)],其结构经元素分析和X-射线单晶衍射表征。1属三斜晶系,空间群P-1,晶胞参数a=10.143 0(9),b=11.900 1(11),c=12.629 9(13),α=111.060(2)°,β=91.070 0(10)°,γ=110.920(2)°,Z=1,V=1 309.8(2)3,F(000)=692。2属单斜晶系,空间群Cc,晶胞参数a=9.860 9(8),b=17.852 9(13),c=13.412 3(15),β=106.583(11)°,Z=4,V=2 263.0(4)3,F(000)=1 256。用荧光光谱和热分析分别研究了1和2的荧光性质和热稳定性,结果表明:在310 nm激发波长激发下,与phen相比,1和2的荧光发射峰分别发生红移和蓝移,λem分别位于451 nm和374 nm。1和2的初始分解温度分别为298℃和300℃。
Two novel multinuclear copper complexes containing N-donor ligand, Cu4 (phen) 4 ( H2 O ) 2 (OH)4 · (NO3)4 ·2H2O(1) and Cu2(phen)2Cl4(2), were synthesized in water by solvent evapo- ration method using 1,10-phenanthroline(phen) as the ligand. The structures were characterized by elemental analysis and X-ray single crystal diffraction. 1 belongs to triclinic system, space group P-1 with a =10.143 0(9) A, b=11.900 1(11) A, c=12.629 9(13) A, a=111.060(2)A, B= 91.070 0(10)A, γ =110.920(2)°, Z =1, V=1309.8(2) A3, F(000) =692. 2 belongs to monoclinic system, space group Cc with a = 9. 860 9 (8) A, b = 17. 852 9 ( 13 ) A, c = 13. 412 3 (15) A, β = 106.583(11)°, Z =4, V=2 263.0(4) A3, F(000) = 1 256. The fluorescent and thermal stability properties of I and 2 were investigated. The results showed that λem of 1 and 2 were 451 nm and 374 nm under 310 nm excitatin, and the initial decomposition temperatures were 298 ℃ and 300 ℃, respectively.
