The compound described by NaCu3Te2 crystallizes in the trigonal R3m space group. Na(1) is bonded in a 8-coordinate geometry to one Cu(1), one Cu(2), three equivalent Te(1), and three equivalent Te(2) atoms. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 11-coordinate geometry to one Na(1), three equivalent Cu(2), three equivalent Cu(3), one Te(1), and three equivalent Te(2) atoms. In the second Cu site, Cu(2) is bonded in a 5-coordinate geometry to one Na(1), three equivalent Cu(1), one Te(2), and three equivalent Te(1) atoms. In the third Cu site, Cu(3) is bonded in a 6-coordinate geometry to three equivalent Cu(1) and three equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), one Cu(1), and three equivalent Cu(2) atoms. In the second Te site, Te(2) is bonded in a 10-coordinate geometry to three equivalent Na(1), one Cu(2), three equivalent Cu(1), and three equivalent Cu(3) atoms. is represented by the CIF file [CIF]
