Nb6BiTe8 crystallizes in the trigonal P-3 space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four equivalent Te(1) atoms. Bi(1) is bonded in a distorted body-centered cubic geometry to two equivalent Bi(1) and six equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to six equivalent Nb(1) atoms to form distorted face-sharing TeNb6 pentagonal pyramids. In the second Te site, Te(1) is bonded in a 4-coordinate geometry to four equivalent Nb(1) and one Bi(1) atom.
