SrCu2As2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent As(1) atoms. Cu(1) is bonded to four equivalent Sr(1) and four equivalent As(1) atoms to form a mixture of distorted edge, face, and corner-sharing CuSr4As4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), four equivalent Cu(1), and one As(1) atom.
