Yb Rh W W
YbW2Rh crystallizes in the trigonal R3m space group. Yb(1) is bonded in a 1-coordinate geometry to three equivalent W(1), three equivalent W(2), and one Rh(1) atom. All Yb(1)-W(1) bond lengths are 2.72 Å. All Yb(1)-W(2) bond lengths are 2.72 Å. The Yb(1)-Rh(1) bond length is 2.14 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 7-coordinate geometry to three equivalent Yb(1), one W(2), and three equivalent Rh(1) atoms. The W(1)-W(2) bond length is 2.14 Å. All W(1)-Rh(1) bond lengths are 2.72 Å. In the second W site, W(2) is bonded in a 5-coordinate geometry to three equivalent Yb(1), one W(1), and one Rh(1) atom. The W(2)-Rh(1) bond length is 2.32 Å. Rh(1) is bonded in a distorted single-bond geometry to one Yb(1), one W(2), and three equivalent W(1) atoms.
