Abstract
Two new mononuclear Schiff base zinc(II) complexes, [Zn (NMP)(MeCOO)] (1) and [ZnBr2(MP)]·MeOH·H2O (2) (NMP = 4-nitro-2-[(3-morpholin-4-ylpropylimino)methyl]phenolate; MP = 2-[(3-morpholin-4-ylpropylimino)methyl]phenolate), have been synthesized from the similar tridentate Schiff base ligands. The complexes were characterized by elemental analysis, infrared spectra, and single-crystal X-ray diffraction. The Zn atom in 1 is five-coordinated in a distorted Squire-pyramidal geometry by the NNO donor set of NMP and two O atoms of an acetate ligand. The Zn atom in 2 is four-coordinated in a tetrahedral geometry by the imino N and phenolate O atoms of MP and two Br atoms. The thermal stability and fluorescence properties of the complexes have also been determined.
