- 中文摘要: The anilinepentacyanoferrate (II) complex has been characterized in aqueous solution. The complex exhibits a predominant ligand field transition at.lambda./sub max/=415nm with . epsilon./sub max/=494M/sup -1/cm/sup -1/. The corresponding Fe(III) complex displays a strong absorption at.lambda./sub max/=700nm(.epsilon./sub max/=1.61*10/sup 4/M/sup -1/sec/sup -1/) which can be assigned as a ligand to metal charge transfer transition. The rate constants of formation and dissociation for the Fe( II) complex are(3.14.plmin.0.18)*10/sup 2/M/sup -1/sec/sup -1/ and 0.985.plmin.0.005 sec/sup -1/, respectively, at .mu.=0.10 M LiClO/sub 4/, pH=8 and T=25.degree.C. The cyclic voltammetry of the complex shows that a reversible redox process is observed with E/sub 1/2/ value of 0.51.plmin.0.01 V vs. NHE at .mu.=0.10 M LiClO/sub 4/, pH=8 and T=25.degree.C. The kinetic study of the oxidation of the Fe(II) complex by ferricyanide ion yielded the rate constant of the reaction k/sub et/=(1.43. plmin.0.04)*10/sup 4/M/sup -1/sec/sup -1/ at .mu.=0.10M LiClO/sub 4/, pH=8 and T=25.degree.C.
