Fe(III)-Complexes with Mixed Ligands Consisting of Oxalate and Phenolate LigandsThe formation of mixed-ligand complexes between iron(III) ion, potassium oxalate and potassium salts of salicylic acid, sulfosalicylic acid, catechol, sodium 3,5-sulfocatechol („tiron“) and tetrachlorocatechol, respectively, has been investigated. There were obtained solid products with the approximate composition K3[Fe(C2O4)3-xLx] · n H2O (L = phenolat; x = 1; 2). For the synthesis of the above compounds ligand exchange reactions as well as addition-technique of oxalic acid followed by potassium phenolat to Fe2O3 · aq has been used. Through spectroscopic examination of the obtained products was found, that Fe3+-ion is simultaneously coordinated by oxalat and phenolat. Probably the products consist of at least two components as Fe(III) was found in two different bond states.
