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.
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. Both Ag(1)-N(1) bond lengths are 2.56 Å. Both Ag(1)-N(2) bond lengths are 2.34 Å. Si(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing SiN4 tetrahedra. The Si(1)-N(2) bond length is 1.70 Å. There are two shorter (1.78 Å) and one longer (1.79 Å) Si(1)-N(1) bond length. 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.
