Materials Data on KSn3 by Materials Project
KSn3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K is bonded to twelve equivalent Sn atoms to form a mixture of distorted face and corner-sharing KSn12 cuboctahedra. There are six shorter (3.63 Å) and six longer (3.80 Å) K–Sn bond lengths. Sn is bonded in a 10-coordinate geometry to four equivalent K and six equivalent Sn atoms. All Sn–Sn bond lengths are 3.20 Å.
