Complexes of sulphadiamidine. Part II. Equilibrium and thermodynamic studies of iron(II) and iron(III) with sulphadiamidine

Article abstract of DOI:10.1080/00945719909349457

Binary complexes of 4-amino-N-(2,6-dimethyl-4-pyrimidinyl)benzensulfonamide (sulphadiamidine) (HL) with Fe(II) and Fe(III) were studied at an ionic strength of 0.1 M KNO₃, and at 25° C. The formation constants of these binary complexes were determined using the MINIQUAD program. The solid complexes were prepared and characterized by elemental analyses, electrolytic conductance, electronic, IR, mass spectra and thermogravimetric (TG, DTG and DTA) measurements. The ligand forms 1:2 complexes (metal:ligand). An octahedral geometry is suggested for the complexes where two coordination sites are occupied by two water molecules or one chloride ion and a water molecule, [ML₂(H₂O)_nCl_m], where M = Fe(II) (n = 2, m = 0) or Fe(III) (n = 1, m = 1) and HL = sulphadiamidine.
