Materials Data on In3(PO4)2 by Materials Project

In3(PO4)2 crystallizes in the cubic I-43d space group. The structure is three-dimensional. In2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are two shorter (2.12 Å) and two longer (2.51 Å) In–O bond lengths. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.55 Å) and one longer (1.58 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent In2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one In2+ and one P5+ atom.

磷酸铟（In₃(PO₄)₂）以立方晶系I-43d空间群结晶，其晶体结构为三维网状结构。铟(II)阳离子（In²+）以畸变矩形跷跷板构型与四个氧阴离子（O²-）成键，铟-氧键键长分为两组：两组较短键长为2.12 Å，另外两组较长键长为2.51 Å。磷(V)阳离子（P⁵+）以四面体构型与四个氧阴离子成键，磷-氧键键长分为两组：三组较短键长为1.55 Å，一组较长键长为1.58 Å。该体系存在两种不等价的氧阴离子位点：在第一种氧阴离子位点中，氧阴离子以畸变单键构型与三个等价的铟(II)阳离子及一个磷(V)阳离子成键；在第二种氧阴离子位点中，氧阴离子以畸变120°弯折构型与一个铟(II)阳离子及一个磷(V)阳离子成键。
