NaCeCuTe4 crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded to four equivalent Cu(1), four equivalent Te(1), and four equivalent Te(2) atoms to form a mixture of edge, corner, and face-sharing NaCu4Te8 cuboctahedra. Ce(1) is bonded in a 9-coordinate geometry to four equivalent Te(1) and five equivalent Te(3) atoms. Cu(1) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Te(2) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to two equivalent Na(1), two equivalent Ce(1), and four equivalent Te(1) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Cu(1) atoms. In the third Te site, Te(3) is bonded to five equivalent Ce(1) atoms to form a mixture of distorted edge and corner-sharing TeCe5 trigonal bipyramids.
