Np(PdGe)2 crystallizes in the tetragonal I4/mmm space group. Np(1) is bonded in a 16-coordinate geometry to eight equivalent Pd(1) and eight equivalent Ge(1) atoms. Pd(1) is bonded to four equivalent Np(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing PdNp4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Np(1), four equivalent Pd(1), and one Ge(1) atom.
