BaPdSn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Sn(2), and eight equivalent Sn(1) atoms. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1), two equivalent Pd(1), and two equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Pd(1), and four equivalent Sn(1) atoms.
BaPdSn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Sn(2), and eight equivalent Sn(1) atoms. There are four shorter (3.88 Å) and one longer (3.94 Å) Ba(1)-Pd(1) bond length. All Ba(1)-Sn(2) bond lengths are 3.63 Å. There are four shorter (3.74 Å) and four longer (3.75 Å) Ba(1)-Sn(1) bond lengths. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Sn(2), and four equivalent Sn(1) atoms. The Pd(1)-Sn(2) bond length is 2.68 Å. All Pd(1)-Sn(1) bond lengths are 2.71 Å. There are two inequivalent Sn sites.
