MgPd is Copper structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two MgPd clusters. Mg(1) is bonded in a single-bond geometry to one Pd(1) atom. The Mg(1)-Pd(1) bond length is 0.81 Å. Pd(1) is bonded in a distorted linear geometry to one Mg(1) and one Pd(1) atom. The Pd(1)-Pd(1) bond length is 0.77 Å.
