Sc Be Hg Rh
BeScRhHg crystallizes in the trigonal R3m space group. Be(1) is bonded in a 2-coordinate geometry to one Sc(1) and four equivalent Rh(1) atoms. The Be(1)-Sc(1) bond length is 2.16 Å. There is one shorter (2.26 Å) and three longer (2.99 Å) Be(1)-Rh(1) bond lengths. Sc(1) is bonded in a 5-coordinate geometry to one Be(1), three equivalent Rh(1), and one Hg(1) atom. All Sc(1)-Rh(1) bond lengths are 2.71 Å. The Sc(1)-Hg(1) bond length is 2.26 Å. Rh(1) is bonded in a 10-coordinate geometry to four equivalent Be(1), three equivalent Sc(1), and three equivalent Hg(1) atoms. All Rh(1)-Hg(1) bond lengths are 2.71 Å. Hg(1) is bonded in a distorted single-bond geometry to one Sc(1) and three equivalent Rh(1) atoms.
