NpGePd2Ge crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NpGe clusters and two Pd2Ge clusters. In each NpGe cluster, Np(1) is bonded in a single-bond geometry to one Ge(2) atom. The Np(1)-Ge(2) bond length is 0.35 Å. Ge(2) is bonded in a single-bond geometry to one Np(1) atom. In each Pd2Ge cluster, Pd(1) is bonded in a distorted single-bond geometry to one Ge(1) atom. The Pd(1)-Ge(1) bond length is 0.53 Å. Ge(1) is bonded in a 2-coordinate geometry to two equivalent Pd(1) atoms.
