Abstract The complexes between different diorganotin cations and substituted 1, 10‐phenanthrolines in aqueous solution containing acetate ion have been investigated. Diorganotin cations can co‐ordinate two acetate ions. One of these may be replaced by a 1, 10‐phenanthroline derivative. A comparison of the different equilibrium constants shows that the acid hardness of diorganotin cations is markedly modified if the organic groups bound to the tin are α,β‐unsaturated.
