Al Os Os Pd
Os2PdAl crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted T-shaped geometry to one Os(2), one Pd(1), and one Al(1) atom. The Os(1)-Os(2) bond length is 1.63 Å. The Os(1)-Pd(1) bond length is 1.74 Å. The Os(1)-Al(1) bond length is 2.78 Å. In the second Os site, Os(2) is bonded in a 3-coordinate geometry to one Os(1) and two equivalent Al(1) atoms. There is one shorter (2.07 Å) and one longer (2.16 Å) Os(2)-Al(1) bond length. Pd(1) is bonded in a 2-coordinate geometry to one Os(1) and one Al(1) atom. The Pd(1)-Al(1) bond length is 2.04 Å. Al(1) is bonded in a 4-coordinate geometry to one Os(1), two equivalent Os(2), and one Pd(1) atom.
