AuSn2 crystallizes in the orthorhombic Pbca space group. Au(1) is bonded to three equivalent Sn(1) and three equivalent Sn(2) atoms to form a mixture of edge and corner-sharing AuSn6 octahedra. The corner-sharing octahedral tilt angles range from 48-66°. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. In the second Sn site, Sn(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms.
