Complex tin(II) acetates

Abstract

The preparations of alkali-metal, ammonium, and alkaline-earth triacetatostannates(II) are described and their solubilities in various solvents are reported. The crystal data on the complexes have been obtained from X-ray-diffraction photographs. Evidence is given for the existence of the species Sn(CH₃·CO₂)⁺, Sn(CH₃·CO₂)₂, Sn₃(CH₃·CO₂)₇^–, Sn₂(CH₃·CO₂)₅^–, and Sn(CH₃·CO₂)₃^– in tin(II)–acetate solutions. The thermal decomposition of the salts has been studied in detail, and their stability to hydrolysis and oxidation reported. The stability of the pyramidal triacetatostannate (II) ion is discussed in terms of the outer electronic configuration of tin(II).
