SbPd2 crystallizes in the orthorhombic Cmc2_1 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to two equivalent Sb(1) and three equivalent Sb(2) atoms. In the third Pd site, Pd(3) is bonded in a 4-coordinate geometry to one Sb(1) and three equivalent Sb(2) atoms. In the fourth Pd site, Pd(4) is bonded in a 4-coordinate geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Pd(3), two equivalent Pd(2), two equivalent Pd(4), and four equivalent Pd(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to two equivalent Pd(4), three equivalent Pd(2), and three equivalent Pd(3) atoms.
SbPd2 crystallizes in the orthorhombic Cmc2_1 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. All Pd(1)-Sb(1) bond lengths are 2.76 Å. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to two equivalent Sb(1) and three equivalent Sb(2) atoms. Both Pd(2)-Sb(1) bond lengths are 2.77 Å. There is one shorter (2.70 Å) and two longer (2.85 Å) Pd(2)-Sb(2) bond lengths. In the third Pd site, Pd(3) is bonded in a 4-coordinate geometry to one Sb(1) and three equivalent Sb(2) atoms. The Pd(3)-Sb(1) bond length is 2.66 Å. There are two shorter (2.64 Å) and one longer (2.70 Å) Pd(3)-Sb(2) bond length. In the fourth Pd site, Pd(4) is bonded in a 4-coordinate geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. There is one shorter (2.63 Å) and one longer (2.68 Å) Pd(4)-Sb(1) bond length. Both Pd(4)-Sb(2) bond lengths are 2.79 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Pd(3), two equivalent Pd(2), two equivalent Pd(4), and four equivalent Pd(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to two equivalent Pd(4), three equivalent Pd(2), and three equivalent Pd(3) atoms.
