Sr(CoAs)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 16-coordinate geometry to eight equivalent Co(1) and eight equivalent As(1) atoms. Co(1) is bonded to four equivalent Sr(1) and four equivalent As(1) atoms to form a mixture of distorted corner, face, and edge-sharing CoSr4As4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Co(1) atoms.
