Abstract

A three-dimensional (3D) Silverton-type polyoxomolybdate (POMo) with the formula of NH₄{Mn₄[PrMo₁₂O₄₂]}·18H₂O (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 {PrMo₁₂O₄₂} has formed 3D frameworks via the {MnO₆} 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.

Keywords: crystal structure; magnetic property; photoluminescence; polyoxomolybdate; silverton-type.
