NaPdAs2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaPdAs2 clusters. Na(1) is bonded in an L-shaped geometry to one Pd(1) and two equivalent As(1) atoms. The Na(1)-Pd(1) bond length is 0.56 Å. Both Na(1)-As(1) bond lengths are 0.41 Å. Pd(1) is bonded in a distorted L-shaped geometry to one Na(1) and two equivalent As(1) atoms. Both Pd(1)-As(1) bond lengths are 0.41 Å. As(1) is bonded in a distorted single-bond geometry to one Na(1) and one Pd(1) atom.
