  Synthesis and supramolecular structures of manganese complexes with N-pyrazolylpropanamide-derived ligands

  摘要：

  The syntheses and single crystal X-ray structures of the multifunctional acrylamide-derived ligands N-pyrazolyl-2-methylpropanamide (1, = N-ppa(Me)) and a mixture of 3- and 5-methylpyrazolylpropanamide (2a and 2b, = N-3(Me)ppa/N-(5Me)ppa), and their Mn2+ complexes are reported, as is the Mn2+ complex of N-triazolylpropanamide (3, = N-tpa). The general synthesis involves treatment of MnCl2 center dot 4H(2)O with the appropriate ligand in solution in the presence of triethylorthoformate as dehydrating agent. This way Mn2Cl4(N-ppa(Me))(2)(EtOH)(2) (4), [Mn(N-(PPa)-P-3Me)(2)(N-(PPa)-P-5Me)][MnCl4] (5), and MnCl2(N-tpa)(2)(EtOH)(2) (6) were obtained. In 4 the N-ppa(Me) ligand acts as N,O-chelating ligand whose oxygens bridge the two Mn2+ ions. The ligands are also chelating in 5. In contrast, monodentate N-coordination via the pyrazolyl ring was found for 6. The molecular and crystal structures of 1, 2a, 4, 5, and 6 have been determined by X-ray diffraction. The extensive hydrogen bonding that occurs in these compounds is discussed. (C) 2014 Elsevier Ltd. All rights reserved.
