| Abstract: | A novel organic–inorganic hybrid, cadmium(II)-magnesium(II)-molybdenum(V) phosphate, {Cd[(PO4)2(HPO4)2Mo6O11(OH)4]2}[Cd(H2O)]2[Mg(Hen)]2{Cd[(PO4)3(HPO4)Mo6O10(OH)3Cl2]2}·(H2en)4·(Hen)2·(en)2·9H2O (en = ethylenediamine), was prepared under hydrothermal conditions and characterized by single-crystal X-ray diffraction, X-ray powder diffraction, elemental analysis, inductively coupled plasma (ICP) analysis, thermogravimetric analysis, fluorescence, FT-IR and bond valence sum calculations. As revealed by single-crystal X-ray diffraction studies, the sandwich-shaped clusters of [Cd(Mo6P4)2] are interconnected by additional [Mg(Hen)] units and [Cd(H2O)] fragments to form an extended three-dimensional supramolecular framework with channels occupied by ethylenediamine molecules, protonated ethylenediamine cations and water molecules. Luminescent measurement of the title compound exhibits intensive blue and greenish-blue radiation emission upon excitation with ultraviolet light. |
