Li Li Sn Hg
Li2HgSn crystallizes in the triclinic P1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 6-coordinate geometry to two equivalent Li(2), two equivalent Hg(1), and two equivalent Sn(1) atoms. There is one shorter (2.22 Å) and one longer (2.62 Å) Li(1)-Li(2) bond length. There is one shorter (2.26 Å) and one longer (2.96 Å) Li(1)-Hg(1) bond length. There is one shorter (2.38 Å) and one longer (3.05 Å) Li(1)-Sn(1) bond length. In the second Li site, Li(2) is bonded in a 6-coordinate geometry to two equivalent Li(1), two equivalent Hg(1), and two equivalent Sn(1) atoms. There is one shorter (2.38 Å) and one longer (3.05 Å) Li(2)-Hg(1) bond length. There is one shorter (2.26 Å) and one longer (2.96 Å) Li(2)-Sn(1) bond length. Hg(1) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and one Sn(1) atom. The Hg(1)-Sn(1) bond length is 1.42 Å. Sn(1) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and one Hg(1) atom.
