摘要
在室温条件下合成了含三核铁簇的硫酸盐配合物K2(H3O)3[Fe3(H2O)3O(SO4)6].6 H2O,借助IR光谱、紫外-可见吸收光谱、X射线光电子能谱(XPS)和X射线单晶衍射等测试手段对其结构进行了表征.结果表明,标题化合物属于六方晶系,P6(3)/m空间群,晶胞参数为:a=b=0.963 7(2)nm,c=1.885 1(9)nm,V=1.516 3(9)nm3,Z=2,Dc=2.316 g/cm3,GOOF=1.089,R1=0.062 8,wR2=0.165 1.其分子由1个三核铁簇阴离子[Fe3(H2O)3O(SO4)6]5-、2个K+离子、3个水合质子H3O+和6个结晶水分子组成.
A sulfate K2（H3O）3[Fe3（H2O）3O（SO4）6]·6H2O containing one trinuclear iron cluster was successfully synthesized at room temperature.Its structure was characterized by means of infrared spectrometry,ultraviolet-visible light spectrophotometry,X-ray photoelectron spectroscopy（XPS） and single-crystal X-ray diffraction.Results indicate that the title compound crystallizes in hexagonal space group P6（3）/m,with cell parameters being a = b = 0.963 7（2） nm,c = 1.885 1（9） nm,V = 1.516 3（9） nm3,Z = 2,Dc = 2.316 g/cm3,GOOF = 1.089,R1 = 0.062 8,and wR2 = 0.165 1.It consists of 1 trinuclear iron cluster anion [Fe3（H2O）3O（SO4）6]5-,2 K＋ cations,3 hydrated protons H3O＋ and 6 lattice water molecules.
