Abstract

Two zinc(II) complexes [ZnI2((2,3-MeO-ba)2en)] (1) and [ZnCl2((2,3-MeO-ba)2en)] (2), with the symmetrical bidentate Schiff-base ligand (2,3-MeO-ba)2en [N,N′-bis(2,3-dimethoxybenzylidene)-1,2-diaminoethane] have been synthesized and characterized by elemental analyses (CHN), FT-IR and 1H-NMR spectroscopy. The thermal behaviors of these complexes were studied using thermogravimetry in order to evaluate their thermal stability and thermal decomposition pathways. The crystal structure of [ZnI2((2,3-MeO-ba)2en)] (1) was determined from single-crystal X-ray diffraction. The coordination polyhedron about the zinc(II) center in the complex 1 is best described as a distorted tetrahedron. Zinc(II) complexes [ZnX2((2,3-MeO-ba)2en)] (X = I (1) and Cl (2)) have been synthesized and characterized by elemental analyses (CHN), FT-IR and 1H-NMR spectroscopy. The crystal structure of 1 was determined from single-crystal X-ray diffraction. The coordination polyhedron about the zinc(II) center in the complex 1 is best described as a distorted tetrahedron.
