AuAg2In crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two AuAg2In ribbons oriented in the (1, 0, 0) direction. Au is bonded in a linear geometry to two equivalent Ag atoms. Both Au–Ag bond lengths are 2.66 Å. Ag is bonded in a linear geometry to one Au and one In atom. The Ag–In bond length is 2.64 Å. In is bonded in a linear geometry to two equivalent Ag atoms.
Au2AgIn is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Au1- is bonded in a body-centered cubic geometry to four equivalent Ag1+ and four equivalent In1+ atoms. All Au–Ag bond lengths are 2.92 Å. All Au–In bond lengths are 2.92 Å. Ag1+ is bonded in a body-centered cubic geometry to eight equivalent Au1- atoms. In1+ is bonded in a body-centered cubic geometry to eight equivalent Au1- atoms.
