The compound described by Nb3AgTe4 crystallizes in the hexagonal P6_3/m space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Te(1) and four equivalent Te(2) atoms. Ag(1) is bonded in a body-centered cubic geometry to two equivalent Ag(1) and six equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to six equivalent Nb(1) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to four equivalent Nb(1) and two equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
