Cu Hg Bi Pd
PdCuHgBi crystallizes in the trigonal R3m space group. Pd(1) is bonded in a 11-coordinate geometry to four equivalent Cu(1), three equivalent Hg(1), and four equivalent Bi(1) atoms. There are three shorter (2.86 Å) and one longer (3.37 Å) Pd(1)-Cu(1) bond length. All Pd(1)-Hg(1) bond lengths are 3.04 Å. There are three shorter (2.86 Å) and one longer (3.37 Å) Pd(1)-Bi(1) bond length. Cu(1) is bonded in a distorted single-bond geometry to four equivalent Pd(1), one Hg(1), and three equivalent Bi(1) atoms. The Cu(1)-Hg(1) bond length is 1.78 Å. All Cu(1)-Bi(1) bond lengths are 3.04 Å. Hg(1) is bonded in a single-bond geometry to three equivalent Pd(1), one Cu(1), and four equivalent Bi(1) atoms. There are three shorter (2.86 Å) and one longer (3.37 Å) Hg(1)-Bi(1) bond length. Bi(1) is bonded in a 11-coordinate geometry to four equivalent Pd(1), three equivalent Cu(1), and four equivalent Hg(1) atoms.
