Materials Data on Sr(InP)2 by Materials Project
SrIn2P2 crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two SrIn2P2 sheets oriented in the (0, 0, 1) direction. Sr2+ is bonded to six equivalent P3- atoms to form edge-sharing SrP6 octahedra. All Sr–P bond lengths are 3.09 Å. In2+ is bonded in a trigonal non-coplanar geometry to three equivalent P3- atoms. All In–P bond lengths are 2.66 Å. P3- is bonded to three equivalent Sr2+ and three equivalent In2+ atoms to form a mixture of edge and corner-sharing PSr3In3 octahedra. The corner-sharing octahedral tilt angles are 0°.
