In3Pd5 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to two equivalent In(2) and four equivalent In(1) atoms. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to one In(2) and four equivalent In(1) atoms. In the third Pd site, Pd(3) is bonded to two equivalent In(2) and four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing PdIn6 cuboctahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to two equivalent Pd(3), four equivalent Pd(1), and four equivalent Pd(2) atoms. In the second In site, In(2) is bonded in a body-centered cubic geometry to two equivalent Pd(2), two equivalent Pd(3), and four equivalent Pd(1) atoms.
In3Pd5 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to two equivalent In(2) and four equivalent In(1) atoms. Both Pd(1)-In(2) bond lengths are 2.70 Å. There are a spread of Pd(1)-In(1) bond distances ranging from 2.74-2.99 Å. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to one In(2) and four equivalent In(1) atoms. The Pd(2)-In(2) bond length is 2.76 Å. There are two shorter (2.80 Å) and two longer (2.83 Å) Pd(2)-In(1) bond lengths. In the third Pd site, Pd(3) is bonded to two equivalent In(2) and four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing PdIn6 cuboctahedra. Both Pd(3)-In(2) bond lengths are 2.84 Å. All Pd(3)-In(1) bond lengths are 2.84 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to two equivalent Pd(3), four equivalent Pd(1), and four equivalent Pd(2) atoms. In the second In site, In(2) is bonded in a body-centered cubic geometry to two equivalent Pd(2), two equivalent Pd(3), and four equivalent Pd(1) atoms.
