Abstract
The title compound, NH(4)YbP(2)O(7), crystallizes in the KAlP(2)O(7) structure type and consists of distorted YbO(6) octa-hedra and bent P(2)O(7) (4-) diphosphate units forming together a three-dimensional network. There are channels in the structure running along the c axis, where the NH(4) (+) cations are located. They are connected via N-H⋯O hydrogen bonds to the terminal O atoms of the diphosphate anions.
摘要
标题化合物NH₄YbP₂O₇以KAlP₂O₇结构类型结晶，由扭曲的YbO₆八面体和弯曲的P₂O₇⁴⁻二磷酸单元共同形成三维网络。结构中存在沿c轴延伸的通道，NH₄⁺阳离子位于其中。它们通过N—H⋯O氢键与二磷酸阴离子的末端O原子相连。
