| الوصف: | A novel three dimensional (3D) coordination polymer [Sm(pic)2(pydc)4(H2O)]n (pydc = pyridine-2,5-dicarboxylate, Hpic = picolinic acid) (1) has been synthesized hydrothermally and characterized by elemental analysis, FT-IR, TG/DTA, single-crystal X-ray diffraction analysis and powder X-ray diffraction (PXRD). This compound crystallizes in the monoclinic space group P21/c with cell parameters a = 9.3041(13) Å, b = 14.216(2) Å, c = 10.5401(15) Å, V = 1387.72(30) Å3 and Z = 4. Complex 1 has a distinct 3D open-framework architecture due to the presence of picolinic ligands, which are converted from 2,5-pydc ligands by in-situ decarboxylation under the hydrothermal conditions. The compound exhibits strong luminescent emissions because of the f-f transitions of the Sm(III) ion at room temperature. According to TGA/DTA analysis, the coordination polymer is thermally stable up to ~300 °C. © 2015 Elsevier Ltd.
