Ag3AuSe2 crystallizes in the cubic I4_132 space group. Au(1) is bonded in a 8-coordinate geometry to six equivalent Ag(1) and two equivalent Se(1) atoms. Ag(1) is bonded in a 6-coordinate geometry to two equivalent Au(1) and four equivalent Se(1) atoms. Se(1) is bonded to one Au(1) and six equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing SeAg6Au hexagonal pyramids.
Ag3AuSe2 crystallizes in the cubic I4_132 space group. Au(1) is bonded in a 8-coordinate geometry to six equivalent Ag(1) and two equivalent Se(1) atoms. All Au(1)-Ag(1) bond lengths are 3.04 Å. Both Au(1)-Se(1) bond lengths are 2.48 Å. Ag(1) is bonded in a 6-coordinate geometry to two equivalent Au(1) and four equivalent Se(1) atoms. There are two shorter (2.76 Å) and two longer (2.88 Å) Ag(1)-Se(1) bond lengths. Se(1) is bonded to one Au(1) and six equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing SeAg6Au hexagonal pyramids.
