Pd2CdAl crystallizes in the monoclinic Cm space group. Pd(1) is bonded in a 3-coordinate geometry to one Pd(1), one Cd(1), and two equivalent Al(1) atoms. The Pd(1)-Pd(1) bond length is 1.16 Å. The Pd(1)-Cd(1) bond length is 1.24 Å. There is one shorter (2.07 Å) and one longer (3.16 Å) Pd(1)-Al(1) bond length. Cd(1) is bonded in a 3-coordinate geometry to two equivalent Pd(1) and one Al(1) atom. The Cd(1)-Al(1) bond length is 1.61 Å. Al(1) is bonded in a 5-coordinate geometry to four equivalent Pd(1) and one Cd(1) atom.
