KPd2Al crystallizes in the monoclinic Cm space group. K(1) is bonded in a 2-coordinate geometry to one Pd(2), three equivalent Pd(1), and one Al(1) atom. The K(1)-Pd(2) bond length is 2.02 Å. There is one shorter (3.39 Å) and two longer (3.98 Å) K(1)-Pd(1) bond lengths. The K(1)-Al(1) bond length is 1.61 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to three equivalent K(1), one Pd(2), and four equivalent Pd(1) atoms. The Pd(1)-Pd(2) bond length is 3.01 Å. All Pd(1)-Pd(1) bond lengths are 3.38 Å. In the second Pd site, Pd(2) is bonded in a 2-coordinate geometry to one K(1), one Pd(1), and one Al(1) atom. The Pd(2)-Al(1) bond length is 2.04 Å. Al(1) is bonded in a 1-coordinate geometry to one K(1) and one Pd(2) atom.
