BaCu2As2 crystallizes in the tetragonal I4/mmm space group. Ba(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 Ba(1) and four equivalent As(1) atoms to form a mixture of distorted edge, face, and corner-sharing CuBa4As4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Cu(1) atoms.
