Ba(CoGe)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ge(1) atoms. Co(1) is bonded to four equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing CoGe4 tetrahedra. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Co(1) atoms.
