FeRhPt4 crystallizes in the trigonal R3m space group. Fe(1) is bonded in a 7-coordinate geometry to four equivalent Pt(2) and six equivalent Pt(1) atoms. There are three shorter (3.15 Å) and one longer (3.22 Å) Fe(1)-Pt(2) bond length. All Fe(1)-Pt(1) bond lengths are 2.80 Å. Rh(1) is bonded in a 6-coordinate geometry to three equivalent Pt(1) and three equivalent Pt(2) atoms. All Rh(1)-Pt(1) bond lengths are 1.87 Å. All Rh(1)-Pt(2) bond lengths are 3.14 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to two equivalent Fe(1), one Rh(1), one Pt(2), and two equivalent Pt(1) atoms. The Pt(1)-Pt(2) bond length is 1.55 Å. Both Pt(1)-Pt(1) bond lengths are 0.89 Å. In the second Pt site, Pt(2) is bonded in a 10-coordinate geometry to four equivalent Fe(1), three equivalent Rh(1), and three equivalent Pt(1) atoms.
