PtZnIn crystallizes in the trigonal R3m space group. Pt(1) is bonded in a 6-coordinate geometry to three equivalent Zn(1) and three equivalent In(1) atoms. All Pt(1)-Zn(1) bond lengths are 2.79 Å. All Pt(1)-In(1) bond lengths are 2.79 Å. Zn(1) is bonded to three equivalent Pt(1) and one In(1) atom to form distorted ZnInPt3 tetrahedra that share corners with three equivalent In(1)ZnPt3 tetrahedra, corners with six equivalent Zn(1)InPt3 tetrahedra, and edges with three equivalent In(1)ZnPt3 tetrahedra. The Zn(1)-In(1) bond length is 1.35 Å. In(1) is bonded to three equivalent Pt(1) and one Zn(1) atom to form distorted InZnPt3 tetrahedra that share corners with three equivalent Zn(1)InPt3 tetrahedra, corners with six equivalent In(1)ZnPt3 tetrahedra, and edges with three equivalent Zn(1)InPt3 tetrahedra.
