Zusammenfassung:An amorphous heterometal salt of aquaamino pyrophosphate of copper (II)-cadmium in the solid state relates to mixed salts - as per composition of anions and coordination salts - as per structure of complex cation, of the general formula of Cu3Cdx(PO4)2(P2O7)x/2.n(NH3).m(H2O), where x=0.86?2.0; n=3.1?3.5; m=5.3?7.4, in which a prescribed ratio between the content of Cu and Cd is obtained on the basis of dissolving mechanical mixture of Cu3(PO4)2.3H2O and Cd2P2O7.5H2O, taken at a ratio of Cu2+:Cd2+ between 1.5:1.0 and 4.0:1.0, at an excess of concentrated aqueous solution of ammonia with subsequent sedimentation of solid compound by addition of acetone and maintaining thereof in the air at 15?25 DEGREE C till complete hardening and constant mass.
