Synthesis and Crystal Structures of Mn(II)- and Ni(II)-Dicarboxylate Complexes with 1,10-Phenanthroline

摘要

Two new metal(II) complexes, [Mn(dpa)(phen)(H2O)2]n (1) (H2dpa = dephenic acid, phen = 1,10-phenanthroline) and [Ni2(nda)(phen)2(H2O)6](nda)(H2O) (2) (H2nda = 2,6-naphthalenedicarboxylic acid) have been synthesized and characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis, and single crystal X-ray diffraction. In complex 1, Mn(II) ion is six-coordinated, and Mn(II) ions are bridged by dpa ligands into 1D chains. While, the complex 2 is dimer and two Ni(II) ions are bridged by one nda ligand cooperated with the terminal ligand phen. In each complex, the dicarboxylate ligand is coordinated to metal(II) ions as a bis-monodentate.
