K Ge Rh Rh
KRh2Ge crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to one Rh(1), three equivalent Rh(2), and four equivalent Ge(1) atoms. The K(1)-Rh(1) bond length is 1.63 Å. All K(1)-Rh(2) bond lengths are 2.70 Å. There is one shorter (2.65 Å) and three longer (2.86 Å) K(1)-Ge(1) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one K(1), one Rh(2), and three equivalent Ge(1) atoms. The Rh(1)-Rh(2) bond length is 2.65 Å. All Rh(1)-Ge(1) bond lengths are 2.70 Å. In the second Rh site, Rh(2) is bonded in a 7-coordinate geometry to three equivalent K(1), one Rh(1), and three equivalent Ge(1) atoms. All Rh(2)-Ge(1) bond lengths are 2.70 Å. Ge(1) is bonded in a 10-coordinate geometry to four equivalent K(1), three equivalent Rh(1), and three equivalent Rh(2) atoms.
