Sb Pd Pd Pd
Pd3Sb crystallizes in the triclinic P1 space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 4-coordinate geometry to one Pd(3), two equivalent Pd(2), and one Sb(1) atom. The Pd(1)-Pd(3) bond length is 2.12 Å. There is one shorter (2.10 Å) and one longer (2.42 Å) Pd(1)-Pd(2) bond length. The Pd(1)-Sb(1) bond length is 2.50 Å. In the second Pd site, Pd(2) is bonded in a 5-coordinate geometry to one Pd(3), two equivalent Pd(1), and two equivalent Sb(1) atoms. The Pd(2)-Pd(3) bond length is 2.50 Å. There is one shorter (2.12 Å) and one longer (3.12 Å) Pd(2)-Sb(1) bond length. In the third Pd site, Pd(3) is bonded in a single-bond geometry to one Pd(1), one Pd(2), and one Sb(1) atom. The Pd(3)-Sb(1) bond length is 0.86 Å. Sb(1) is bonded in a distorted single-bond geometry to one Pd(1), one Pd(3), and two equivalent Pd(2) atoms.
