Abstract: The effects of structural differences on the reactions of α-, β-, and γ-[Cu(NH₃)₂(C₂O₄)] with gaseous and liq. NH₃ to give [Cu(NH₃)₅(C₂O₄)] were studied. Three different modifications of [Cu(NH₃)₅(C₂O₄)] were formed and the thermal decompns. of each gave that modification of [Cu(NH₃)₂(C₂O₄)] from which the pentaammine was formed. The ammonation reactions started by substitution of the O atom on the long coordinate in α- and β- [Cu(NH₃)₂(C₂O₄)] and by occupying the free coordination positions in γ-[Cu(NH₃)₂(C₂O₄)].
