Mn2PtAuSb2 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 to one Pt(1), three equivalent Au(1), three equivalent Sb(1), and three equivalent Sb(2) atoms to form distorted MnSb6PtAu3 tetrahedra that share corners with six equivalent Mn(2)Sb6Pt3Au tetrahedra, faces with six equivalent Mn(2)Sb6Pt3Au tetrahedra, and faces with six equivalent Mn(1)Sb6PtAu3 tetrahedra. In the second Mn site, Mn(2) is bonded to three equivalent Pt(1), one Au(1), three equivalent Sb(1), and three equivalent Sb(2) atoms to form distorted MnSb6Pt3Au tetrahedra that share corners with six equivalent Mn(1)Sb6PtAu3 tetrahedra, faces with six equivalent Mn(2)Sb6Pt3Au tetrahedra, and faces with six equivalent Mn(1)Sb6PtAu3 tetrahedra. Pt(1) is bonded in a body-centered cubic geometry to one Mn(1), three equivalent Mn(2), one Sb(2), and three equivalent Sb(1) atoms. Au(1) is bonded in a body-centered cubic geometry to one Mn(2), three equivalent Mn(1), one Sb(1), and three equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 10-coordinate geometry to three equivalent Mn(1), three equivalent Mn(2), three equivalent Pt(1), and one Au(1) atom. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to three equivalent Mn(1), three equivalent Mn(2), one Pt(1), and three equivalent Au(1) atoms.
