Abstract: The title compound, NH₄YbP₂O₇, crystallizes in the KAlP₂O₇ structure type and consists of distorted YbO₆ octahedra and bent P₂O₇^4- diphosphate units forming together a three-dimensional network. There are channels in the structure running along the c axis, where the NH₄⁺ cations are located. They are connected via N-HO hydrogen bonds to the terminal O atoms of the diphosphate anions.
