Abstract: | Two types of monoligand complexes of FeCl3, Fe(NO3)3 and Fe2(SO4)3 with hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC) were prepared and characterized. Elemental analysis, UV and IR spectro-scopies, conductance and magnetic measurements were used to assign the mode of coordination in the isolated species. The investigation revealed that Fe(III ) exhibits tetrahedral coordination with HEC and CMC. These ligands act as a bidentate chelating agent via the two oxygen atoms of the vicinal hydroxyl and ether groups (ethoxyl or carboxymethyl groups). The prepared complexes have the formula (HEC) FeCl]Cl, (HEC) FeNO3]NO3, (HEC)FeSO4·H2O]H2O, (CMC)FeCl·H2O]Cl·2H2O, (CMC)Fe·2NO3]3H2O and (CMC)-FeSO4·H2O]H2O. The results also showed that the type of cellulose ether (functional group) and the anion of the metal salts used have an effect on the conductivity, structure and absorptivity of Fe(III ) complexes. © of SCI. |
