Cd Ag Hg Bi
AgHgCdBi crystallizes in the trigonal R3m space group. Ag(1) is bonded in a distorted single-bond geometry to one Cd(1) and three equivalent Bi(1) atoms. The Ag(1)-Cd(1) bond length is 2.08 Å. All Ag(1)-Bi(1) bond lengths are 3.00 Å. Hg(1) is bonded to three equivalent Cd(1) and one Bi(1) atom to form HgCd3Bi trigonal pyramids that share  a cornercorner with one Cd(1)AgHg3Bi trigonal bipyramid and corners with six equivalent Hg(1)Cd3Bi trigonal pyramids. All Hg(1)-Cd(1) bond lengths are 3.00 Å. The Hg(1)-Bi(1) bond length is 2.08 Å. Cd(1) is bonded to one Ag(1), three equivalent Hg(1), and one Bi(1) atom to form distorted CdAgHg3Bi trigonal bipyramids that share corners with six equivalent Cd(1)AgHg3Bi trigonal bipyramids and  a cornercorner with one Hg(1)Cd3Bi trigonal pyramid. The Cd(1)-Bi(1) bond length is 2.08 Å. Bi(1) is bonded in a 5-coordinate geometry to three equivalent Ag(1), one Hg(1), and one Cd(1) atom.
