ABSTRACT
New ferrous complexes of antibiotic drug compounds (Sulfaclozine and
Thiamphenicol) were synthesized with Fe:Ln molar ratio of 1:2. The
complexes were characterized by elemental analyses, IR, UV–vis. spectra,
magnetic and thermal instruments. The results of the molar conductance
measurements reveal that all the complexes have no electrolytic behavior.
The infrared spectra show that both drug ligands act as a bidentate
chelate, Sulfaclozine coordinates through sulfonyl oxygen atoms
and pyrazine nitrogen, while the Thiamphenicol ligand bind toward Fe
(II) ion via both hydroxyl oxygen atom. The spectroscopic results suggest
octahedral geometry for all Fe (II) complexes. The kinetic thermodynamic
parameters of the essential DTGmax decomposition steps were calculated.
The evaluation of cytotoxicity of Fe (II) complexes against HCT-116 and
MCF-7 cell line were performed. Moreover, the antimicrobial activities
(bacteria) of the complexes were assessed in comparison with the ligand.
