K Ru Ru Rh
KRu2Rh crystallizes in the monoclinic Cm space group. K(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1), four equivalent Ru(2), and one Rh(1) atom. There are a spread of K(1)-Ru(1) bond distances ranging from 3.76-3.83 Å. There are a spread of K(1)-Ru(2) bond distances ranging from 2.29-2.40 Å. The K(1)-Rh(1) bond length is 3.29 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to four equivalent K(1), four equivalent Ru(1), and four equivalent Rh(1) atoms to form a mixture of corner and face-sharing RuK4Ru4Rh4 cuboctahedra. All Ru(1)-Ru(1) bond lengths are 3.03 Å. There are a spread of Ru(1)-Rh(1) bond distances ranging from 3.12-3.21 Å. In the second Ru site, Ru(2) is bonded in a 4-coordinate geometry to four equivalent K(1) and four equivalent Rh(1) atoms. There are a spread of Ru(2)-Rh(1) bond distances ranging from 3.12-3.21 Å. Rh(1) is bonded in a 13-coordinate geometry to one K(1), four equivalent Ru(1), four equivalent Ru(2), and four equivalent Rh(1) atoms. All Rh(1)-Rh(1) bond lengths are 3.03 Å.
