K4RhSb crystallizes in the trigonal R3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 3-coordinate geometry to two equivalent K(1), three equivalent Rh(1), and one Sb(1) atom. Both K(1)-K(1) bond lengths are 1.91 Å. There are two shorter (3.89 Å) and one longer (4.23 Å) K(1)-Rh(1) bond length. The K(1)-Sb(1) bond length is 2.99 Å. In the second K site, K(2) is bonded in a distorted trigonal non-coplanar geometry to four equivalent Rh(1) atoms. There are three shorter (3.91 Å) and one longer (4.17 Å) K(2)-Rh(1) bond length. Rh(1) is bonded in a 13-coordinate geometry to four equivalent K(2) and nine equivalent K(1) atoms. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent K(1) atoms.
