3D supramolecular networks of Mn(II)-5-sulfosalicylate assembled with 4,4′-dipyridyl N,N′-dioxide and 4,4′-dipyridyl: Structure, photoluminescence and DFT calculations

Crystal structure of poly[diaqua-μ5-4-(3,5-dicarboxylato-κ 3 O 1:O 2:O 3-phenoxy)phthalato-κ 3 O 5,O 7:O 8)(μ2-4-(1H-pyrazol-5-yl)pyridine-κ

“…However, it still remains a great and long-term challenge to predict exactly the molecular structure and property of coordination polymers because of many subtle factors involved in the formation and crystallization process such as the geometries of the metal ions (node) and ligands (linker), supramolecular interaction, and reaction conditions [5]. One strategy is to perform reactions with mixed-ligands such as polycarboxylate and N-containing ligands in the same system, and a great number of novel intriguing structures are obtained [6][7][8][9], which indicates that the introduction of N-containing auxiliary ligands into a metal-polycarboxylate system often leads to structural diversity and a ords novel frameworks. The asymmetric unit of the title structure contains two Co(II) ions, and 4-(3,5-dicarboxylato-phenoxy)phthalato as well as 4-(1H-pyrazol-5-yl)pyridine as bridging ligands to construct a coordination polymer.…”

“…11 The syntheses of various supramolecular compounds enhance our knowledge about intermolecular interactions and thus aid design and synthesis of new supramolecular structures. 12 The Mn(II) ion is frequently used in constructing inorganic supramolecular molecules 13 since manganese-based complexes have potential applications of their optical and magnetic properties in catalysis and biological studies. 14 The electrochemical behaviour of [Mn(terpy) 2 ] +2 ions in acetonitrile solution demonstrate oxidation of Mn(II) to Mn(III) at +1.28 V relative to the standard calomel electrode.…”
