Unstable intermediates. Part LXXX. An electron spin resonance investigation of the [Ag–Cd]2+ and Cd23+ diatomic cations

Abstract

Exposure of frozen aqueous acids and alcohols containing Cd²⁺ salts to γ-rays at low temperatures results in the formation of a species which has the properties expected for Cd⁺. When the matrices are annealed, this reacts with excess Cd² to from the diatomic Cd₂³⁺. In environments containing excess of Ag⁺ ions the analogous species [Ag–Cd]²⁺ is formed when the matrix is warmed.
