The results of physicochemical analyzes of the compound CuNH4 PO4 ∙ H2O isolated from ammophos pulp at pH 6.58 obtained by neutralization of phosphoric acid containing copper sulfate as a trace element with gaseous ammonia are presented. The compound was found to have the formula [Cu (NH3) (H2O) HPO4]. The parameters of the N–H bond for the coordinated amino group were calculated: force constant, bond angle, and interatomic distance. In the transition from the electronic spectrum of the reflection of copper hydrophosphate monohydrate to the spectrum of copper ammonium phosphate monohydrate, a hypochromic shift of a maximum of 74 nm is observed, which indicates the entry of an ammonia molecule into the composition of copper monoaquahydrophosphate with the formation of copper monoaquaaminehydrophosphate. This is confirmed by the absence of an intense wide band at 3100-2900 sm- 1 characteristic of the ammonium cation in the IR spectrum.
