The material structure described by AgSi2N3 crystallizes in the orthorhombic Cmc2_1 space group. Ag(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and 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 to one Ag(1) and three equivalent Si(1) atoms to form distorted corner-sharing NSi3Ag trigonal pyramids. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
