Abstract A new cobalt complex, [Co(L)2·(H2O)2](HL = 4-hexanoyl-3-methyl-1-phenyl-1H -pyrazol-5(4H)-one), was synthesized by us. The complex was characterized by single crystal X-ray diffraction, IR, UV, fluorescence spectra and thermogravimetric analysis. The results of characterization showed that the crystal is monoclinic system with crystal parameters: a = 15.2439(12) A, b = 7.4101(6) A, c = 15
摘要 我们合成了一种新的钴配合物[Co(L)2·(H2O)2](HL = 4-己酰基-3-甲基-1-苯基-1H-吡唑-5(4H)-one)。通过单晶X射线衍射、红外、紫外、荧光光谱和热重分析对该配合物进行了表征。表征结果表明该晶体为单斜晶系,晶体参数为:a=15.2439(12)A,b=7.4101(6)A,c=15.7381(18)A,Z=2,S=1.074。发现Co2+位于复合体的反演中心。Co(II) 具有理想的八面体配位环境,在赤道平面上有四个 HL 配体的氧原子,在轴向位置有两个水分子。由于来自配体内发射激发态的荧光,该复合物呈现黄色发射。
