K K Y Hg
K2YHg is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2YHg cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted single-bond geometry to one Hg(1) atom. The K(1)-Hg(1) bond length is 0.58 Å. In the second K site, K(2) is bonded in a 2-coordinate geometry to one Y(1) and one Hg(1) atom. The K(2)-Y(1) bond length is 0.34 Å. The K(2)-Hg(1) bond length is 0.46 Å. Y(1) is bonded in an L-shaped geometry to one K(2) and one Hg(1) atom. The Y(1)-Hg(1) bond length is 0.34 Å. Hg(1) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one Y(1) atom.
