| Abstract: | 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. |
