K K Sc Rh
K2ScRh 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 1.91 Å. There is one shorter (3.00 Å) and two longer (3.91 Å) K(1)-Rh(1) bond lengths. In the second K site, K(2) is bonded in a 1-coordinate geometry to one K(1) and one Sc(1) atom. The K(2)-Sc(1) bond length is 2.45 Å. Sc(1) is bonded in a distorted single-bond geometry to one K(2) and one Rh(1) atom. The Sc(1)-Rh(1) bond length is 1.32 Å. Rh(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Sc(1) atom.
