The crystal structure described by KAg3Te2 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(3), three equivalent Ag(2), one Te(2), and two equivalent Te(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 5-coordinate geometry to one K(1), two equivalent Ag(1), one Te(1), and one Te(2) atom. In the second Ag site, Ag(2) is bonded in a 9-coordinate geometry to three equivalent K(1), one Ag(3), two equivalent Ag(2), and three equivalent Te(2) atoms. In the third Ag site, Ag(3) is bonded in a 7-coordinate geometry to one K(1), one Ag(2), one Ag(3), two equivalent Te(1), and two equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a pentagonal planar geometry to two equivalent K(1), one Ag(1), and two equivalent Ag(3) atoms. In the second Te site, Te(2) is bonded in a 7-coordinate geometry to one K(1), one Ag(1), two equivalent Ag(3), and three equivalent Ag(2) atoms. is represented by the CIF file [CIF]
