YPd2 is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YPd2 cluster. Y(1) is bonded in a distorted water-like geometry to one Pd(1) and one Pd(2) atom. The Y(1)-Pd(1) bond length is 1.54 Å. The Y(1)-Pd(2) bond length is 2.00 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Y(1) atom. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Y(1) atom.
