The material structure described by KSn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 12-coordinate geometry to three equivalent Sn(1) and nine equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to six equivalent K(1) and six equivalent Sn(2) atoms to form a mixture of edge, corner, and face-sharing SnK6Sn6 cuboctahedra. In the second Sn site, Sn(2) is bonded to six equivalent K(1), two equivalent Sn(1), and four equivalent Sn(2) atoms to form a mixture of edge, corner, and face-sharing SnK6Sn6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
