BaPdGe3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Ge(2), and eight equivalent Ge(1) atoms. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Pd(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Pd(1), and four equivalent Ge(1) atoms.
BaPdGe3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Ge(2), and eight equivalent Ge(1) atoms. There are four shorter (3.59 Å) and one longer (3.67 Å) Ba(1)-Pd(1) bond length. All Ba(1)-Ge(2) bond lengths are 3.43 Å. There are four shorter (3.45 Å) and four longer (3.48 Å) Ba(1)-Ge(1) bond lengths. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Ge(2), and four equivalent Ge(1) atoms. The Pd(1)-Ge(2) bond length is 2.62 Å. All Pd(1)-Ge(1) bond lengths are 2.54 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Pd(1), and two equivalent Ge(2) atoms. Both Ge(1)-Ge(2) bond lengths are 2.73 Å. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Pd(1), and four equivalent Ge(1) atoms.
