The material described by Ag2Te crystallizes in the monoclinic Pc space group. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted hexagonal planar geometry to one Ag(4), two equivalent Ag(2), one Te(2), and two equivalent Te(1) atoms. In the second Ag site, Ag(2) is bonded in a 8-coordinate geometry to two equivalent Ag(1), two equivalent Ag(3), one Te(2), and three equivalent Te(1) atoms. In the third Ag site, Ag(3) is bonded to two equivalent Ag(2), one Te(1), and three equivalent Te(2) atoms to form AgAg2Te4 tetrahedra that share corners with four equivalent Te(1)Ag7 hexagonal pyramids, corners with four equivalent Ag(3)Ag2Te4 tetrahedra,  an edgeedge with one Te(1)Ag7 hexagonal pyramid, and edges with two equivalent Ag(3)Ag2Te4 tetrahedra. In the fourth Ag site, Ag(4) is bonded in a 4-coordinate geometry to one Ag(1), one Te(1), and three equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one Ag(3), one Ag(4), two equivalent Ag(1), and three equivalent Ag(2) atoms to form distorted TeAg7 hexagonal pyramids that share corners with four equivalent Te(1)Ag7 hexagonal pyramids, corners with four equivalent Ag(3)Ag2Te4 tetrahedra, edges with two equivalent Te(1)Ag7 hexagonal pyramids, and  an edgeedge with one Ag(3)Ag2Te4 tetrahedra. In the second Te site, Te(2) is bonded in a body-centered cubic geometry to one Ag(1), one Ag(2), three equivalent Ag(3), and three equivalent Ag(4) atoms. is represented by the CIF file [CIF]
