The material structure described by NaAu3Si crystallizes in the cubic Pa-3 space group. Na(1) is bonded in a 16-coordinate geometry to one Na(1), twelve equivalent Au(1), and three equivalent Si(1) atoms. Au(1) is bonded in a 12-coordinate geometry to four equivalent Na(1), six equivalent Au(1), and two equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to three equivalent Na(1) and six equivalent Au(1) atoms. is represented by the CIF card [CIF]
