Al P P Pd
PdAlP2 crystallizes in the triclinic P1 space group. Pd(1) is bonded in a single-bond geometry to one Al(1) and two equivalent P(1) atoms. The Pd(1)-Al(1) bond length is 0.53 Å. There is one shorter (2.61 Å) and one longer (2.69 Å) Pd(1)-P(1) bond length. Al(1) is bonded in a single-bond geometry to one Pd(1), two equivalent P(1), and two equivalent P(2) atoms. There is one shorter (2.92 Å) and one longer (3.00 Å) Al(1)-P(1) bond length. There is one shorter (2.61 Å) and one longer (2.69 Å) Al(1)-P(2) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to two equivalent Pd(1), two equivalent Al(1), and two equivalent P(2) atoms. There is one shorter (1.88 Å) and one longer (2.59 Å) P(1)-P(2) bond length. In the second P site, P(2) is bonded in a 3-coordinate geometry to two equivalent Al(1) and two equivalent P(1) atoms.
