PdSn2 crystallizes in the tetragonal I4_1/acd space group. Pd(1) is bonded in a 9-coordinate geometry to one Pd(1), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to four equivalent Pd(1) and one Sn(1) atom. In the second Sn site, Sn(2) is bonded to four equivalent Pd(1) atoms to form a mixture of distorted corner and edge-sharing SnPd4 tetrahedra.
PdSn2 crystallizes in the tetragonal I4_1/acd space group. Pd(1) is bonded in a 9-coordinate geometry to one Pd(1), four equivalent Sn(1), and four equivalent Sn(2) atoms. The Pd(1)-Pd(1) bond length is 2.87 Å. All Pd(1)-Sn(1) bond lengths are 2.85 Å. There are two shorter (2.83 Å) and two longer (2.84 Å) Pd(1)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to four equivalent Pd(1) and one Sn(1) atom. The Sn(1)-Sn(1) bond length is 2.93 Å. In the second Sn site, Sn(2) is bonded to four equivalent Pd(1) atoms to form a mixture of distorted corner and edge-sharing SnPd4 tetrahedra.
