The material structure described by Pd7Te2 crystallizes in the trigonal R-3m space group. There are five inequivalent Pd sites. In the first Pd site, Pd(5) is bonded in a 14-coordinate geometry to six equivalent Pd(2), six equivalent Pd(4), and two equivalent Te(1) atoms. In the second Pd site, Pd(1) is bonded in a 11-coordinate geometry to one Pd(3), two equivalent Pd(1), two equivalent Pd(2), three equivalent Pd(4), one Te(1), one Te(2), and one Te(3) atom. In the third Pd site, Pd(2) is bonded in a 7-coordinate geometry to one Pd(3), one Pd(5), two equivalent Pd(1), three equivalent Pd(4), and two equivalent Te(3) atoms. In the fourth Pd site, Pd(3) is bonded in a 1-coordinate geometry to three equivalent Pd(1), three equivalent Pd(2), and one Te(1) atom. In the fifth Pd site, Pd(4) is bonded in a 1-coordinate geometry to one Pd(5), three equivalent Pd(1), three equivalent Pd(2), and one Te(1) atom. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to one Pd(3), one Pd(5), three equivalent Pd(1), and three equivalent Pd(4) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to six equivalent Pd(1) atoms. In the third Te site, Te(3) is bonded in a 6-coordinate geometry to two equivalent Pd(1) and four equivalent Pd(2) atoms. is represented by the CIF card [CIF]
