Li Ag Ag Hg
LiAg2Hg crystallizes in the monoclinic Cm space group. Li(1) is bonded in a 7-coordinate geometry to four equivalent Li(1), two equivalent Ag(2), and one Hg(1) atom. All Li(1)-Li(1) bond lengths are 3.28 Å. There is one shorter (3.26 Å) and one longer (3.47 Å) Li(1)-Ag(2) bond length. The Li(1)-Hg(1) bond length is 3.24 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to four equivalent Ag(2) and one Hg(1) atom. There are a spread of Ag(1)-Ag(2) bond distances ranging from 1.68-2.96 Å. The Ag(1)-Hg(1) bond length is 0.61 Å. In the second Ag site, Ag(2) is bonded in a 10-coordinate geometry to two equivalent Li(1), four equivalent Ag(1), and four equivalent Hg(1) atoms. There are a spread of Ag(2)-Hg(1) bond distances ranging from 1.75-2.99 Å. Hg(1) is bonded in a single-bond geometry to one Li(1), one Ag(1), and four equivalent Ag(2) atoms.
