KRh2Bi crystallizes in the trigonal R3m space group. K(1) is bonded in a 1-coordinate geometry to four equivalent Rh(1), six equivalent Rh(2), and one Bi(1) atom. There are three shorter (2.94 Å) and one longer (3.21 Å) K(1)-Rh(1) bond length. There are three shorter (3.25 Å) and three longer (3.72 Å) K(1)-Rh(2) bond lengths. The K(1)-Bi(1) bond length is 2.38 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to four equivalent K(1) and four equivalent Rh(2) atoms to form distorted edge-sharing RhK4Rh4 tetrahedra. There are three shorter (2.94 Å) and one longer (3.21 Å) Rh(1)-Rh(2) bond length. In the second Rh site, Rh(2) is bonded in a 14-coordinate geometry to six equivalent K(1), four equivalent Rh(1), and four equivalent Bi(1) atoms. There are three shorter (2.94 Å) and one longer (3.21 Å) Rh(2)-Bi(1) bond length. Bi(1) is bonded in a distorted single-bond geometry to one K(1) and four equivalent Rh(2) atoms.
