Sažetak (engleski)
Equilibrium and kinetic studies were performed to investigate the complexation of aqueous high spin iron(III) by hydroxyurea H2NC(O)NH(OH) in acidie solutions at 25 <c and I = 2.0 mol dm? (maintained by NaC104). Complexation has been interpreted in terms of coordination of the N-O oxygen atom and the NH2 nitrogen atom of the ligand to the iron(III) ion with concomitant loss of a proton yielding the complex of the molar ratio 1 :1. The equilibrium quotient for the formation of mono(hydroxyureato)iron (III) complex is found to be Kl = 1.4. The kinetic results suggest a parallel path mechanism involving substitution on Fe(H20)63+ and Fe(H20l50H2+ by the hydroxyurea, HU: Fe (HzO)63+ + HU ;;= Fe (HzO)4 U2++ H+ Fe (H20)s (OH)2++ HU;;=' Fe (HzO)4 U2' The formation of the complex occurs by the rate constants kl = 16.8 M-l S-I and k1' = 5450 M" S-I. The analogous rate eonstants for the reverse hydrolysis reactions were obtained as k-l = = 11.8 M-l S-I and k_1' = 6.3 S-I. The results are compared with kinetic data previously reported for the different mono(hydroxamato) iron(III) complexes.
