Y In Hg Hg
YHg2In crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YHg2In clusters. Y(1) is bonded in a single-bond geometry to one Hg(1) atom. The Y(1)-Hg(1) bond length is 1.41 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a bent 120 degrees geometry to one Y(1) and one In(1) atom. The Hg(1)-In(1) bond length is 1.51 Å. In the second Hg site, Hg(2) is bonded in a distorted single-bond geometry to one In(1) atom. The Hg(2)-In(1) bond length is 1.51 Å. In(1) is bonded in a bent 120 degrees geometry to one Hg(1) and one Hg(2) atom.
