Tm5Pd2Bi crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded to four equivalent Pd(1) and two equivalent Bi(1) atoms to form distorted corner-sharing TmBi2Pd4 octahedra. The corner-sharing octahedral tilt angles range from 0-48°. In the second Tm site, Tm(2) is bonded in a 5-coordinate geometry to three equivalent Pd(1) and two equivalent Bi(1) atoms. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Tm(1) and six equivalent Tm(2) atoms. Bi(1) is bonded in a distorted q6 geometry to two equivalent Tm(1) and eight equivalent Tm(2) atoms.

In the first Tm site, Tm(1) is bonded to four equivalent Pd(1) and two equivalent Bi(1) atoms to form distorted corner-sharing TmBi2Pd4 octahedra. The corner-sharing octahedral tilt angles range from 0-48°. All Tm(1)-Pd(1) bond lengths are 2.97 Å. Both Tm(1)-Bi(1) bond lengths are 3.39 Å. In the second Tm site, Tm(2) is bonded in a 5-coordinate geometry to three equivalent Pd(1) and two equivalent Bi(1) atoms. There are two shorter (2.94 Å) and one longer (2.95 Å) Tm(2)-Pd(1) bond length. Both Tm(2)-Bi(1) bond lengths are 3.26 Å. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Tm(1) and six equivalent Tm(2) atoms. Bi(1) is bonded in a distorted q6 geometry to two equivalent Tm(1) and eight equivalent Tm(2) atoms.
