BaCo2As2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent As(1) atoms. Co(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted edge and corner-sharing CoAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Co(1) atoms.
