Cr Cd Hg
CrHgCd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrHgCd cluster. Cr(1) is bonded in a bent 120 degrees geometry to one Hg(1) and one Cd(1) atom. The Cr(1)-Hg(1) bond length is 1.78 Å. The Cr(1)-Cd(1) bond length is 1.32 Å. Hg(1) is bonded in a distorted single-bond geometry to one Cr(1) atom. Cd(1) is bonded in a distorted single-bond geometry to one Cr(1) atom.
