以3,3’,4,4’-偶氮苯四羧酸(ABTC)和1,10-菲罗啉(phen)为配体,金属Zn(Ⅱ)为配位中心,采用溶剂挥发法在乙醇水中合成了新型夹心双核配合物[Zn2(ABTC)(phen)2(H2O)6·2H2O(1)],其结构和荧光性能经元素分析,X-射线单晶衍射和FL表征。1属单斜晶系,空间群C12/c1(15),晶胞参数a=24.774(3),b=12.853 8(13),c=14.698 3(15),β=94.195(2)°,V=4 668.0(8)3,Dc=1.584 Mg·cm-3,Z=24,F(000)=2 232,μ=43.083 mm-1,Goo F=0.969,R1=0.164 2,ωR2=0.047 3。ABTC作为桥梁配体,夹在两个配位中心中间。通过两个游离的水分子及配位分子的氢键作用,堆积成三维超分子孔道结构。在280 nm激发波长激发下,1在415 nm处有强的荧光发射峰。
The metal Zn (Ⅱ) was coordinated by 3,3 ’, 4,4’-azobenzenetetracarboxylic acid (ABTC) and 1,10-phenanthroline (phen) A novel sandwich dinuclear complex [Zn2 (ABTC) (phen) 2 (H2O) 6 · 2H2O (1)] was synthesized in ethanol and its structure and fluorescence properties were characterized by elemental analysis, X-ray single crystal diffraction and FL. 1 is a monoclinic with a space group of C12 / c1 (15) with unit cell parameters of a = 24.774 (3) , b = 12.853 8 (13) and c = 14.698 3 ) °, V = 4 668.0 (8) 3, Dc = 1.584 Mg · cm -3, Z = 24, F (000) = 2 232, μ = 43.083 mm -1, Goo F = 0.969, R 1 = 0.164 2 , ωR2 = 0.047 3. ABTC as a bridge ligand, sandwiched between two coordination centers. Through the two hydrogen bonds of free water molecules and coordination molecules, they accumulate into three-dimensional supramolecular pore structure. At 280 nm excitation wavelength, 1 has a strong fluorescence emission peak at 415 nm.
