KRh4Pt crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to three equivalent Rh(1), three equivalent Rh(2), and one Pt(1) atom. All K(1)-Rh(1) bond lengths are 2.85 Å. All K(1)-Rh(2) bond lengths are 3.05 Å. The K(1)-Pt(1) bond length is 1.74 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent Rh(1) atoms. All Rh(2)-Rh(1) bond lengths are 1.30 Å. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to one K(1), one Rh(2), two equivalent Rh(1), and one Pt(1) atom. Both Rh(1)-Rh(1) bond lengths are 0.75 Å. The Rh(1)-Pt(1) bond length is 1.50 Å. Pt(1) is bonded in a single-bond geometry to one K(1) and three equivalent Rh(1) atoms.
