本文报道了以钕、钐、铕、铽为包覆层的ε-Keggin多氧钼酸盐的合成及其与六重氰酸盐连接的多维材料[PMo12O37(OH)3{Ln(H2O)5(Fe(CN)6)0.25}4] （Ln = Nd, Sm, Eu，和Tb）的合成。Ln = Nd体系的单晶x射线衍射测量结果显示其为多层结构（正交，Pmmn）。磁性测量表明，这四种化合物由于每个lnii中心而表现出顺磁性。此外，电化学反应还显示出可逆的Mo(V)/Mo（VI）氧化还原行为。
We report the syntheses of ε-Keggin polyoxomolybdates capped by neodymium, samarium, europium and terbium and the corresponding multidimensional materials connected with hexacyanoferrate, [PMo12O37(OH)3{Ln(H2O)5(Fe(CN)6)0.25}4] (Ln = Nd, Sm, Eu, and Tb). The single crystal X-ray diffraction measurement of the Ln = Nd system reveals a multilayered structure (orthorhombic,Pmmn). The magnetic measurement showed that these four compounds exhibit paramagnetism due to each LnIIIcentre. In addition, the electrochemistry shows the reversible Mo(V)/Mo(VI) redox behaviour.
