Abstract
Three new coordination polymers ((CH3)(2)NH2)[Sc(H2O)(2)(fdc)(2)]center dot 1,5CH(3)CN (1), ((CH3)(2)NH2)(2)[Sc(fdc)(2)(HCOO)] (2), [Sc-2(H2O)(2)(fdc)(3)] (3) based on scandium cations and 2,5-furandicarboxylate ligand (fdc(2-)) have been synthesized and characterized by single crystal and powder X-ray diffraction crystallography, TG, elemental analyses and IR-spectroscopy. Compound 1 is formed from layers bind by hydrogen bonds. Calculated accessible for solvent volume is 41%. Compound 2 is a structure of negatively charged layers connected with interlayer dimethylammonium cations. Layered compound 3 appeared to be thermally stable (up to 300 degrees C) and retain its structure in wide range of pH from 1 to 13. Additionally, the solid-state luminescence properties of compounds 2 and 3 we investigated. (C) 2018 Elsevier Ltd. All rights reserved.
