Two Manganese(II) Supramolecular Complexes Based on Imidazole Dicarboxylates: Syntheses, Crystal Structures, and Properties

Two novel Mn(II) complexes [Mn(MDPhH2IDC)(2)(H2O)(2)] (n) (1) (MDPhH3IDC = 2-(3,4-methylenedioxyphenyl)-1H-imidazole-4, 5-dicarboxylic acid), [Mn( m-CPhH3IDC)(2)(H2O)(2)] (n) (2) (m-CPh H4IDC = 2-(3-carboxylphenyl)-1H-imidazole-4,5-dicarboxylic acid) have been hydrothermally synthesized with two kinds of imidazole dicarboxylate ligands, respectively, and structurally characterized by elemental analyses, IR spectra, as well as single crystal X-ray diffraction analysis. The 3D solid-state supramolecular structures of the complexes involve intermolecular hydrogen bonds. Furthermore, the thermal and photoluminescent properties of the complexes have been investigated.
