KOsSn2 crystallizes in the triclinic P1 space group. K(1) is bonded in a 5-coordinate geometry to one Os(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. The K(1)-Os(1) bond length is 2.62 Å. There are a spread of K(1)-Sn(1) bond distances ranging from 2.21-3.24 Å. There are a spread of K(1)-Sn(2) bond distances ranging from 3.03-3.84 Å. Os(1) is bonded in a 1-coordinate geometry to one K(1) and two equivalent Sn(2) atoms. There is one shorter (2.92 Å) and one longer (3.44 Å) Os(1)-Sn(2) bond length. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 2.77 Å. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to three equivalent K(1), two equivalent Os(1), one Sn(1), and two equivalent Sn(2) atoms. Both Sn(2)-Sn(2) bond lengths are 3.30 Å.
