Four structurally intriguing members of a new family of lanthanide (Ln)-containing organophosphonate-functionalized polyoxotungstates with the general formula K[Ln(HO)(AsWO)(WO)(OPCOHCHPO)Ln(HO)]·15HO [Ln = Ce (1Ce), Nd (2Nd), Sm (3Sm) and Eu (4Eu)] were directly isolated by controlling the reaction parameters and well established by single-crystal X-ray diffraction, PXRD analyses, IR spectra, elemental analyses, TG and EDX analyses. All the four three-dimensional frameworks consist of the S-shaped inorganic building block {[(AsWO)(WO)]}, two organophosphonate groups {OPCOHCHPO} and four Ln ions. The magnetic properties of the four compounds and the solid-state photoluminescence properties of 2Nd, 3Sm, and 4Eu were also fully investigated.
