Abstract: In the hydrolysis of solid α-, β-, and γ-Cu(C₂O₄)(NH₃)₂, the max. pH attained, its rate of attainment, and the compn. of the reaction products varied only slightly between the α and βforms, but markedly between these and the γ form, which hydrolyzed to a homogeneous product Cu(C₂O₄)(NH₃). The structure of the γ form is probably square-planar units with trans NH₃ groups and connected by the C₂O₄ groups in linearchains. The high reactivity of the γ form is due to the weak interaction between individual chains and between planes.
