La Ag Hg Hg
LaAgHg2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 2-coordinate geometry to one Ag(1), two equivalent Hg(1), and two equivalent Hg(2) atoms. The La(1)-Ag(1) bond length is 1.82 Å. There is one shorter (2.21 Å) and one longer (2.78 Å) La(1)-Hg(1) bond length. There is one shorter (2.74 Å) and one longer (3.36 Å) La(1)-Hg(2) bond length. Ag(1) is bonded in a single-bond geometry to one La(1) and one Hg(2) atom. The Ag(1)-Hg(2) bond length is 2.76 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 3-coordinate geometry to two equivalent La(1) and one Hg(2) atom. The Hg(1)-Hg(2) bond length is 2.18 Å. In the second Hg site, Hg(2) is bonded in a 4-coordinate geometry to two equivalent La(1), one Ag(1), and one Hg(1) atom.
