The material structure described by AuSi2N3 crystallizes in the orthorhombic Cmc2_1 space group. Au(1) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. Si(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing SiN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to three equivalent Si(1) atoms. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
