Re Ag Hg
ReAgHg crystallizes in the monoclinic Cm space group. Re(1) is bonded in a single-bond geometry to one Ag(1) and one Hg(1) atom. The Re(1)-Ag(1) bond length is 0.69 Å. The Re(1)-Hg(1) bond length is 3.50 Å. Ag(1) is bonded in a single-bond geometry to one Re(1) and one Hg(1) atom. The Ag(1)-Hg(1) bond length is 2.86 Å. Hg(1) is bonded in a 6-coordinate geometry to one Re(1), one Ag(1), and four equivalent Hg(1) atoms. All Hg(1)-Hg(1) bond lengths are 2.80 Å.
