摘要：
Kinetics and equilibria for the reaction between cyanide and iron(II) hexadecachlo rophthalocyanine ((Cl)(16)PcFe(DMSO)(2), where Pc(-2) = phthalocyanine dianion) in dimethyl sulphoxide (DMSO) are reported. Only the spectrophotometric changes due to the formation of the dicyano, [(Cl)(16)PcFe(CN)(2)](2-), complex were observed. This complex is formed with the equilibrium constant, K-3 = 1.6 x 10(3) dm(3) mol(-1) and a rate constant of k(3f) = 4.2 x 10(-3) dm(3) mol(-1) s(-1). The K-2[(Cl)(16)PcFe(CN)(2)] complex dissolves in DMSO and dimethyl formamide (DMF) with epsilon = 110 000 and 92 000 dm(3) mol(-1) cm(-1) respectively.
