Poly[tetraaquatriglutaratodicerium(III) decahydrate], a novel luminescent metal-organic framework possessing hydrophilic hexagonal channels

Abstract

A novel 2D metal-organic framework poly[tetraaquatriglutaratodicerium(III) decahydrate] with an open framework structure has been successfully grown by single gel diffusion technique. Sodium metasilicate was used for gel preparation. The structure was determined by single crystal X-ray diffraction. The compound crystallizes in orthorhombic space group Pnma and possesses a structure consisting of [CeO 10 ] polyhedra and H 2 O molecules with hydrophilic hexagonal channels. The crystals were further characterized by elemental analysis, FT-IR and UV-Visible spectroscopy, powder X-ray diffraction and thermogravimetry. The luminescent property and magnetic susceptibility of the complex were also investigated.
