Ba Co Hg Rh
BaRhCoHg crystallizes in the trigonal R3m space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Rh(1), four equivalent Co(1), and six equivalent Hg(1) atoms. There are three shorter (3.01 Å) and one longer (3.06 Å) Ba(1)-Rh(1) bond length. There are three shorter (3.01 Å) and one longer (3.06 Å) Ba(1)-Co(1) bond length. There are three shorter (3.45 Å) and three longer (3.54 Å) Ba(1)-Hg(1) bond lengths. Rh(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ba(1) and four equivalent Hg(1) atoms. There are three shorter (3.01 Å) and one longer (3.06 Å) Rh(1)-Hg(1) bond length. Co(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Hg(1) atoms. There is one shorter (2.91 Å) and three longer (3.07 Å) Co(1)-Hg(1) bond lengths. Hg(1) is bonded in a 14-coordinate geometry to six equivalent Ba(1), four equivalent Rh(1), and four equivalent Co(1) atoms.
