摘要
在水溶液中合成了一个新的锰取代杂多化合物Cs5[PW11O39Mn(II)(H2O)]的单晶.通过元素分析、红外光谱和X-射线单晶衍射确定了其组成和结构.标题化合物属于四方晶系,空间群P42/ncm,P离子配位数为4,处于变形四面体的配位环境中;W和Mn离子配位数为6,处于变形八面体的配位环境中.其磁性研究结果表明,该化合物具有顺磁性.
Mn-substituted heteropoly Compound Cs5[PW11O39Mn(Ⅱ)(H2O)(H2O)7 has been synthesized by solution method and characterized by element analysis, IR spectra, CV, and the crystal]structure was determined by single-crystal X-ray diffraction. The crystal of the title compound belongs to Tetragonal system, space group P42/ncm, with a= 2.09670(14) nm, b=2.09670(14) nm, c=10.3520(7) nm, V=4.5509(5)nm^3, Z=4, Mr=3540.94, Dc=5.168g·cm^3, F(000)= 6084, μ=32.035mm^-1, R1=0.0510, wR2=0.1332. Tha central P ion has tetrahedronal distortions. W and Mn ions have octahedral distortions. The research of magnetic property shows the title compound is paramagnetic.
