Pd2CdTl crystallizes in the monoclinic Cm space group. Pd(1) is bonded in a single-bond geometry to two equivalent Cd(1) and one Tl(1) atom. There is one shorter (2.36 Å) and one longer (2.87 Å) Pd(1)-Cd(1) bond length. The Pd(1)-Tl(1) bond length is 1.31 Å. Cd(1) is bonded in a 5-coordinate geometry to four equivalent Pd(1) and one Tl(1) atom. The Cd(1)-Tl(1) bond length is 2.21 Å. Tl(1) is bonded in a distorted L-shaped geometry to two equivalent Pd(1) and one Cd(1) atom.
