Materials Data on Cu3SnAu by Materials Project
AuCu3Sn crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Au is bonded in a 12-coordinate geometry to nine equivalent Cu and three equivalent Sn atoms. There are a spread of Au–Cu bond distances ranging from 2.68–3.00 Å. All Au–Sn bond lengths are 2.79 Å. Cu is bonded in a 10-coordinate geometry to three equivalent Au, four equivalent Cu, and three equivalent Sn atoms. There are two shorter (2.64 Å) and two longer (2.65 Å) Cu–Cu bond lengths. There are one shorter (2.71 Å) and two longer (2.87 Å) Cu–Sn bond lengths. Sn is bonded in a 12-coordinate geometry to three equivalent Au and nine equivalent Cu atoms.
