The material described by Mn2RhPtSb2 is half-Heusler-derived structured and crystallizes in the trigonal R3m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 10-coordinate geometry to three equivalent Rh(1), three equivalent Pt(1), one Sb(1), and three equivalent Sb(2) atoms. In the second Mn site, Mn(2) is bonded in a 10-coordinate geometry to three equivalent Rh(1), three equivalent Pt(1), one Sb(2), and three equivalent Sb(1) atoms. Rh(1) is bonded in a 10-coordinate geometry to three equivalent Mn(1), three equivalent Mn(2), one Sb(1), and three equivalent Sb(2) atoms. Pt(1) is bonded in a 10-coordinate geometry to three equivalent Mn(1), three equivalent Mn(2), one Sb(2), and three equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a body-centered cubic geometry to one Mn(1), three equivalent Mn(2), one Rh(1), and three equivalent Pt(1) atoms. In the second Sb site, Sb(2) is bonded in a body-centered cubic geometry to one Mn(2), three equivalent Mn(1), three equivalent Rh(1), and one Pt(1) atom. is represented by the CIF file [CIF]
