A three-dimensional (3D) Silverton-type polyoxomolybdate (POMo) with the formula of NH{Mn[PrMoO]}·18HO (1) was successfully isolated and well characterized by single crystal X-ray diffraction, X-ray powder diffraction pattern, infrared spectrum, thermogravimetric and elemental analyses. The inorganic building block {PrMoO} has formed 3D frameworks the {MnO} linker. The excitation of compound 1 in solid state at 375 nm displays red emission. Moreover, variable temperature magnetic susceptibility measurements indicate that the magnetic behavior in compound 1 is dominated by antiferromagnetic interactions.
成功分离出一种三维（3D）银顿型多钼酸盐（POMo），其化学式为NH{Mn[PrMoO]}·18HO（1），并通过单晶X射线衍射、X射线粉末衍射图谱、红外光谱、热重分析和元素分析对其进行了充分表征。无机结构单元{PrMoO}通过{MnO}连接体形成了三维框架。化合物1在固态下于375nm处激发显示出红色发射。此外，变温磁化率测量表明，化合物1中的磁行为主要由反铁磁相互作用主导。
