以3,5-二硝基苯甲酸,咪唑为配体,合成了新化合物[Cd(H2O)2(DNBA)(Im)2](DNBA)·H2O,(DNBA=3,5-二硝基苯甲酸阴离子)。该配合物属正交晶系,空间群为Ccc2,晶胞参数:a=1.324 99(4)nm,b=1.516 01(5)nm,c=2.789 22(8)nm;V=5.602 7(3)nm3,Dc=1.719 g·cm-3,Z=8,μ=0.866 mm-1,F(000)=2 912,最终偏离因子R1=0.058 3,wR2=0.146 4。该配合物中包含两个单核镉(Ⅱ)配合物,且配合物中还包含未配位的3,5-二硝基苯甲酸,金属中心均是六配位变形八面体结构。并测定和研究了标题化合物的热重和荧光性能。
New compounds [DN (DNBA) · H2O] (DNBA = 3,5-dinitrophenyl) were synthesized using 3,5-dinitrobenzoic acid and imidazole as ligands Benzoate anion). The complex belongs to the orthorhombic system with space group Ccc2. The unit cell parameters are: a = 1.324 99 (4) nm, b = 1.516 01 (5) nm, c = 2.789 22 3) nm3, Dc = 1.719 g · cm-3, Z = 8, μ = 0.866 mm-1, F (000) = 2 912 and the final deviation factor R1 = 0.058 3 and wR2 = 0.146 4. The complex contains two mononuclear cadmium (Ⅱ) complexes, and the complexes also contain uncoordinated 3,5-dinitrobenzoic acid. The metal centers are hexacoordinated distorted octahedral structures. The thermogravimetry and fluorescence properties of the title compounds were determined and studied.
