This work, described, the ligands derived from the condensation of S- methyl dithiocarbazate with 5-acetyl-4-hydroxy-2H-1,3-thiazine-2,6(3H)-dione (AHTD) afforded the dibasic tridentate ONS Schiff base, H2L, ligand. The ligands were allowed to react with some transition metal ions, Ligands and their complexes have been characterized on the basis of elemental analyses, spectroscopy and thermal gravimetric analysis (TGA) as well as the magnetic susceptibility and molar conductivity measurements suggesting dibasic ONS tridentate donors. The proposed structures of complexes were geometrically optimized and their structural parameters were calculated and correlated with the experimental data. Antimicrobial screening of the free ligand and its complexes in vitro towards bacteria and fungus showed pronounced activity for Cu(II) and Cd(II) complexes.
Юль, побольше бы таких людей как Вы отзывчивая, спокойная на моя курсовую работу на другом сайте ответили в таком тоне: "не нравится не заказывайте, если не нравится" ...очень не красиво с их стороны...я бы вообще не обращалась бы к подобным услугам если бы не дети и не очная форма обучения(((даже обидно(((
