KSn2 crystallizes in the triclinic P1 space group. K(1) is bonded in a 4-coordinate geometry to two equivalent Sn(1) and two equivalent Sn(2) atoms. There is one shorter (3.27 Å) and one longer (3.57 Å) K(1)-Sn(1) bond length. There is one shorter (2.96 Å) and one longer (3.50 Å) K(1)-Sn(2) bond length. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Sn(2) atoms. There are a spread of Sn(1)-Sn(2) bond distances ranging from 2.61-2.96 Å. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Sn(1) atoms.
