K K Y Rh
K2YRh crystallizes in the monoclinic Cm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to one K(2) and three equivalent Rh(1) atoms. The K(1)-K(2) bond length is 1.68 Å. There is one shorter (3.32 Å) and two longer (4.03 Å) K(1)-Rh(1) bond lengths. In the second K site, K(2) is bonded in a 2-coordinate geometry to one K(1) and one Y(1) atom. The K(2)-Y(1) bond length is 2.98 Å. Y(1) is bonded in a single-bond geometry to one K(2) and one Rh(1) atom. The Y(1)-Rh(1) bond length is 0.61 Å. Rh(1) is bonded in a single-bond geometry to three equivalent K(1) and one Y(1) atom.
