PtAgSn crystallizes in the trigonal R3m space group. Pt(1) is bonded in a distorted hexagonal planar geometry to three equivalent Ag(1) and three equivalent Sn(1) atoms. All Pt(1)-Ag(1) bond lengths are 2.74 Å. All Pt(1)-Sn(1) bond lengths are 2.74 Å. Ag(1) is bonded to three equivalent Pt(1) and one Sn(1) atom to form distorted AgSnPt3 tetrahedra that share corners with three equivalent Sn(1)AgPt3 tetrahedra, corners with six equivalent Ag(1)SnPt3 tetrahedra, and edges with three equivalent Sn(1)AgPt3 tetrahedra. The Ag(1)-Sn(1) bond length is 1.92 Å. Sn(1) is bonded to three equivalent Pt(1) and one Ag(1) atom to form distorted SnAgPt3 tetrahedra that share corners with three equivalent Ag(1)SnPt3 tetrahedra, corners with six equivalent Sn(1)AgPt3 tetrahedra, and edges with three equivalent Ag(1)SnPt3 tetrahedra.
