The compound described by BaAg2Te2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 12-coordinate geometry to two equivalent Ag(1), three equivalent Ag(2), three equivalent Te(1), and four equivalent Te(2) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Ag(1), one Te(1), and three equivalent Te(2) atoms. In the second Ag site, Ag(2) is bonded to three equivalent Ba(1), one Te(2), and three equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing AgBa3Te4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1), one Ag(1), and three equivalent Ag(2) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), one Ag(2), and three equivalent Ag(1) atoms. is represented by the CIF file [CIF]
