Description
Summary: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. Graphical Abstract Single crystals of a new 2D metal–organic framework, poly[tetraaquatriglutaratodicerium(III) decahydrate] with an open framework structure has been grown by single gel diffusion technique. The compound crystallizes in orthorhombic crystal system, space group Pnma . Single crystal X-ray diffraction study revealed the polymeric structure of the compound. One of the interesting characteristics of the structure is the presence of hydrophilic hexagonal channels. The luminescence and magnetic susceptibility of the complex were also studied.
