Title: Preparation, Characterization and Structural Determination of some coordination compounds of quadridentae thiosemicarbazone
Author: Amin, Ragab R.; El Niel, Abdelraziq E. Hamed; Shedaiwa, Iman
Abstract: New transtion metal complexes of Co", Ni" and Cu" with benzil bis 4-(p-Chlorophenyl-thiosemicarbazone) and benzil bis 4-(p-Bromophenyl-thiosemicarbazone) were synthesized. Attempts were made to ascertain their probable structures on the basis of elemental analysis, infrared and electronic spectra, thermal and magnetic studies. Ligands can function as a binegative quadridentate with the metal ions forming com¬plexes in a molar ratio 1:1 having the formula (ML and ML.2H2O). The magnetic moment measurements and the crystal field parameters calculated for Co11 and Ni" complexes agree well with that reported for known octahedral complexes.
