title: Cyanide thermodynamics 2. Stability constants of copper(I) cyanide complexes in aqueous acetonitrile mixtures.
abstract: The stability (formation) constants of the binary Cu(I)-CN(-) complexes have been measured in five aqueous mixtures containing from 10% to 70% v/v acetonitrile (MeCN) by glass electrode potentiometry at 25 degrees C and an ionic strength of l M (NaClO(4)). The constants show monotonic increases with MeCN concentration, the changes being greatest for the higher order complexes, consistent with the unfavourable solvation of CN (-) in these mixtures. The sparing solubility of CuCN(s) prevented determination of the stability constant for CuCN (0) (soln.) at low MeCN concentrations.
