Cd Ag Hg C
AgHgCdC crystallizes in the trigonal R3m space group. Ag(1) is bonded in a single-bond geometry to four equivalent Hg(1), three equivalent Cd(1), and one C(1) atom. There are three shorter (2.72 Å) and one longer (3.41 Å) Ag(1)-Hg(1) bond length. All Ag(1)-Cd(1) bond lengths are 2.70 Å. The Ag(1)-C(1) bond length is 0.60 Å. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Ag(1), three equivalent Cd(1), and three equivalent C(1) atoms. All Hg(1)-Cd(1) bond lengths are 2.70 Å. All Hg(1)-C(1) bond lengths are 2.70 Å. Cd(1) is bonded in a distorted q6 geometry to three equivalent Ag(1), three equivalent Hg(1), and three equivalent C(1) atoms. All Cd(1)-C(1) bond lengths are 2.72 Å. C(1) is bonded in a single-bond geometry to one Ag(1), three equivalent Hg(1), and three equivalent Cd(1) atoms.
