ABSTRACT=<p>A three-dimensional (3D) Silverton-type polyoxomolybdate (POMo) with the formula of NH<sub>4</sub>{Mn<sub>4</sub>[PrMo<sub>12</sub>O<sub>42</sub>]}·18H<sub>2</sub>O (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 {PrMo<sub>12</sub>O<sub>42</sub>} has formed 3D frameworks <italic>via</italic> the {MnO<sub>6</sub>} 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.</p>
