Pd20Te7 crystallizes in the trigonal R-3 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(4) is bonded in a 3-coordinate geometry to one Pd(1), two equivalent Pd(3), and three equivalent Te(2) atoms. In the second Pd site, Pd(1) is bonded in a 10-coordinate geometry to one Pd(1), three equivalent Pd(2), three equivalent Pd(4), and three equivalent Te(2) atoms. In the third Pd site, Pd(2) is bonded in a 3-coordinate geometry to one Pd(1), four equivalent Pd(3), one Te(1), and two equivalent Te(2) atoms. In the fourth Pd site, Pd(3) is bonded in a 12-coordinate geometry to two equivalent Pd(3), two equivalent Pd(4), four equivalent Pd(2), one Te(1), and three equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a cuboctahedral geometry to six equivalent Pd(2) and six equivalent Pd(3) atoms. In the second Te site, Te(2) is bonded in a 9-coordinate geometry to one Pd(1), two equivalent Pd(2), three equivalent Pd(3), and three equivalent Pd(4) atoms.
