K K Cr Rh
K2CrRh crystallizes in the monoclinic Cm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted single-bond geometry to one K(2) and one Rh(1) atom. The K(1)-K(2) bond length is 1.29 Å. The K(1)-Rh(1) bond length is 3.97 Å. In the second K site, K(2) is bonded in a 2-coordinate geometry to one K(1), one Cr(1), and one Rh(1) atom. The K(2)-Cr(1) bond length is 2.93 Å. The K(2)-Rh(1) bond length is 4.15 Å. Cr(1) is bonded in a 1-coordinate geometry to one K(2) and one Rh(1) atom. The Cr(1)-Rh(1) bond length is 3.50 Å. Rh(1) is bonded in a 7-coordinate geometry to one K(1), one K(2), one Cr(1), and four equivalent Rh(1) atoms. All Rh(1)-Rh(1) bond lengths are 3.48 Å.
