K K Li Os
K2LiOs crystallizes in the triclinic P1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to two equivalent K(2) and two equivalent Li(1) atoms. There is one shorter (1.64 Å) and one longer (2.31 Å) K(1)-K(2) bond length. There is one shorter (2.35 Å) and one longer (3.40 Å) K(1)-Li(1) bond length. In the second K site, K(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Os(1) atom. The K(2)-Os(1) bond length is 3.40 Å. Li(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Os(1) atom. The Li(1)-Os(1) bond length is 1.63 Å. Os(1) is bonded in a distorted single-bond geometry to one K(2) and one Li(1) atom.
