-
In order to find the regularity of the effect of solvent properties on the stability of crown ether coordination compounds, the stability constant logK of the complex formed by crown ether 15C5 with metal cations such as Pb2+, Co2+, Ni2+, Cu2+ and other metal cations in the mixed solvent of methanol (MeOH) and acetonitrile (MeCN), ethanol (EtOH) and acetonitrile (MeCN) was further determined, and the regularity of the influence of solvent properties on the stability of complexes was further studied. The relationship between the stability constant logK of the complex and the molar fraction x of acetonitrile in the mixed solvent was obtained
