SrPdAs2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrPdAs2 clusters. Sr(1) is bonded in a 2-coordinate geometry to one Pd(1) and two equivalent As(1) atoms. The Sr(1)-Pd(1) bond length is 1.53 Å. Both Sr(1)-As(1) bond lengths are 1.21 Å. Pd(1) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent As(1) atoms. Both Pd(1)-As(1) bond lengths are 1.21 Å. As(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Pd(1) atom.
