Polycrystalline material of the title compound, AgInP(2)O(7), was synthesized by traditional high-temperature solid-state methods and single crystals were grown from the melt of a mixture of AgInP(2)O(7) and B(2)O(3) as flux in a platinium crucible. The structure consists of InO(6) octa-hedra, which are corner-shared to PO(4) tetra-hedra into a three-dimensional network with hexa-gonal channels running parallel to the c axis. The silver cation, located in the channel, is bonded to seven O atoms of the [InP(2)O(7)] framework with Ag-O distances ranging from 2.370 (2) to 3.015 (2) Å. The P(2)O(7) diphosphate anion is characterized by a P-O-P angle of 137.27 (9) and a nearly eclipsed conformation. AgInP(2)O(7) is isotypic with the M(I)FeP(2)O(7) (M(I) = Na, K, Rb, Cs and Ag) diphosphate family.
通过传统高温固态方法合成了标题化合物AgInP₂O₇的多晶材料，并在铂坩埚中从AgInP₂O₇与助熔剂B₂O₃的混合物熔体中生长出单晶。其结构由InO₆八面体组成，这些八面体通过角共享与PO₄四面体连接成三维网络，其中六边形通道平行于c轴。位于通道中的银阳离子与[InP₂O₇]骨架的七个O原子键合，Ag - O距离范围为2.370 (2)至3.015 (2) Å。P₂O₇二磷酸根阴离子的特征是P - O - P角为137.27 (9) 以及近乎重叠的构象。AgInP₂O₇与M(I)FeP₂O₇（M(I) = Na、K、Rb、Cs和Ag）二磷酸盐家族同型。
