  Synthesis, crystal structures and properties of two complexes constructed from in situ-generated new ligands

  摘要：

  Two coordination complexes [Mn(ENA)(2)(H2O)(0.5)](n) (1) and [Mn(EPDA)](n) (2) have been synthesized and characterized by elemental analysis, IR, UV, TGA, DSC, PXRD and single crystal X-ray diffraction (ENA = 5-ethylnicotinate acid, EPDA = 5-ethylpyridine-2,3-dicarboxylic acid). In initial studies, Pmmi-ENA was selected to construct supramolecular compounds with metal ions (Pmmi = 5-isopropyl-2-methoxy-5methylimidazolidin- 4-one group). However, the Pmmi group was unexpectedly removed to result in the formation of a new ligand ENA, which coordinated with Mn(II) ions to form a 3D framework 1. In order to further investigate this interesting reaction, the same experiment was carried out with the homologous Imoi-ENA instead of Pmmi-ENA (Imoi-ENA and Pmmi-ENA are the homologous imazethapyr). Interestingly, the Imoi group was also removed, however, two different ligands ENA and EPDA were generated (Imoi = 2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro)-1H-imidazol-2-yl group). In addition, the photoluminescent properties of the two compounds were investigated in the solid state at room temperature. (C) 2012 Elsevier B. V. All rights reserved.
