Np(PdGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Np is bonded in a 8-coordinate geometry to eight equivalent Pd and eight equivalent Ge atoms. All Np–Pd bond lengths are 3.38 Å. All Np–Ge bond lengths are 3.21 Å. Pd is bonded to four equivalent Np and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing PdNp4Ge4 tetrahedra. All Pd–Ge bond lengths are 2.53 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Np, four equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.45 Å.
