Materials Data on KSnSb by Materials Project
KSnSb is Molybdenite-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is two-dimensional and consists of two KSnSb sheets oriented in the (0, 0, 1) direction. K1+ is bonded in a 3-coordinate geometry to three equivalent Sb3- atoms. All K–Sb bond lengths are 3.59 Å. Sn2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sb3- atoms. All Sn–Sb bond lengths are 2.94 Å. Sb3- is bonded to three equivalent K1+ and three equivalent Sn2+ atoms to form distorted edge-sharing SbK3Sn3 octahedra.
