The invention relates to novel chemical compounds of coordination structure, namely to the cuprum (II), zinc and cadmium triple salt with ammonia and orthophosphate and pyrophosphate ions in solid amorphous state of general formula CuZnCd(PO)(PO)4.0NH3.1HO. The process for the preparation of amorphous triple salt of cuprum (II)-zinc-cadmium aquaaminoorthopyrophosphate consists in solving of mechanical mixture of crystalline Cu(PO)5HO, Zn(РO)4НO and Сd(РO)5НО, taken in molar ratio Cu: Zn: Cd= 1.0 : 1.0 : 1.0, in concentrated aqua ammonia with a further sedimentation of solid compound by pouring of ammonia solution of phosphates to the acetone, separation of bottom phase and its keeping on air at 15-25 °С to full solodification and constant weight. |
