The material described by (Nb3Te4)2Zn is Hazelwoodite-derived structured and crystallizes in the trigonal P-3 space group. The structure consists of one 7440-66-6 atom inside a Nb3Te4 framework. In the Nb3Te4 framework, Nb(1) is bonded in a 6-coordinate geometry to two equivalent Te(2) and four 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) atoms. is represented by the CIF file [CIF]
