Hf2Pd2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to six equivalent Pd(1) and four equivalent In(1) atoms. In the second Hf site, Hf(2) is bonded in a 6-coordinate geometry to six equivalent Pd(1) and four equivalent In(1) atoms. Pd(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), and two equivalent In(1) atoms. In(1) is bonded in a 14-coordinate geometry to four equivalent Hf(1), four equivalent Hf(2), four equivalent Pd(1), and two equivalent In(1) atoms.
Hf2Pd2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 6-coordinate geometry to six equivalent Pd(1) and four equivalent In(1) atoms. There are two shorter (2.73 Å) and four longer (2.84 Å) Hf(1)-Pd(1) bond lengths. All Hf(1)-In(1) bond lengths are 3.29 Å. In the second Hf site, Hf(2) is bonded in a 6-coordinate geometry to six equivalent Pd(1) and four equivalent In(1) atoms. There are two shorter (2.74 Å) and four longer (2.79 Å) Hf(2)-Pd(1) bond lengths. All Hf(2)-In(1) bond lengths are 3.21 Å. Pd(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1), three equivalent Hf(2), and two equivalent In(1) atoms. Both Pd(1)-In(1) bond lengths are 2.93 Å. In(1) is bonded in a 14-coordinate geometry to four equivalent Hf(1), four equivalent Hf(2), four equivalent Pd(1), and two equivalent In(1) atoms. Both In(1)-In(1) bond lengths are 3.38 Å.
