The invention relates to the new chemical compounds of coordination structure, namely to the nickel (II)-zinc-cadmium triple salt with ammonia and orthophosphate ion in solid crystal state of general formula NiZnCd(PO)2.0NH2.9HO. The process for the preparation of crystal aquaaminocuprum (II)-zinc-cadmium orthophosphate triple salt, in which fixed ratio between the content of metals is provided by solving of mechanical mixture of crystal Ni(РО)8НО, Zn(PO)4HO and Сd(РО)5НО, taken in mole ratio NiO : ZnO : CdO = 0.75 : 0.75 : 1.5, in surplus of concentrated aqueous solution of ammonia with the further sedimentation of solid compound by infusion of ammonia solution of phosphates to the acetone and its holding on air at the temperature of 15-25 °С to full hardening and constant weight.
