A novel Dy(III)-based organodiphosphonate-functionalized polyoxomolybdate [NH2(CH3)(2)](3){[Dy(DMF)(2) (H2O)(4)](3)[Dy(DMF)(3){(Mo3O8)(O3PCOCH3PO3)}(3)}(2))center dot 6DMF center dot 2H(2)O (1) (DMF = N,N-Dimethylformamide) has been synthesized and characterized by elemental analysis, IR spectrum, thermogravimetric analysis (TG), UV spectroscopy, fluorescence spectroscopy and single-crystal powder X-ray diffraction (PXRD). Compound 1 is composed of two monocapped [Dy(DMF)(3){(Mo3O8)(O3PCOCH3PO3)}(3)](6-) subunits and three [Dy(DME)(2)(H2O)(4)](3+) coordination cations, which contain an internal capsule. The UV spectra indicate that compound 1 is stable in the pH range of 2.76-4.75. (C) 2013 Elsevier B.V. All rights reserved.
