Y Cr Hg Rh
YCrRhHg crystallizes in the trigonal R3m space group. Y(1) is bonded in a single-bond geometry to one Cr(1), three equivalent Rh(1), and four equivalent Hg(1) atoms. The Y(1)-Cr(1) bond length is 0.91 Å. All Y(1)-Rh(1) bond lengths are 2.83 Å. There are three shorter (2.78 Å) and one longer (3.61 Å) Y(1)-Hg(1) bond length. Cr(1) is bonded in a single-bond geometry to one Y(1), three equivalent Rh(1), and three equivalent Hg(1) atoms. All Cr(1)-Rh(1) bond lengths are 2.78 Å. All Cr(1)-Hg(1) bond lengths are 2.83 Å. Rh(1) is bonded in a distorted q6 geometry to three equivalent Y(1), three equivalent Cr(1), and three equivalent Hg(1) atoms. All Rh(1)-Hg(1) bond lengths are 2.78 Å. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Y(1), three equivalent Cr(1), and three equivalent Rh(1) atoms.
