Cr Cr Ag Hg
Cr2AgHg is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cr2AgHg cluster. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to one Cr(2), one Ag(1), and one Hg(1) atom. The Cr(1)-Cr(2) bond length is 0.58 Å. The Cr(1)-Ag(1) bond length is 0.74 Å. The Cr(1)-Hg(1) bond length is 0.86 Å. In the second Cr site, Cr(2) is bonded in a 3-coordinate geometry to one Cr(1), one Ag(1), and one Hg(1) atom. The Cr(2)-Ag(1) bond length is 0.86 Å. The Cr(2)-Hg(1) bond length is 0.74 Å. Ag(1) is bonded in a 2-coordinate geometry to one Cr(1), one Cr(2), and one Hg(1) atom. The Ag(1)-Hg(1) bond length is 0.58 Å. Hg(1) is bonded in a 2-coordinate geometry to one Cr(1), one Cr(2), and one Ag(1) atom.
