The crystal structure described by CoGe crystallizes in the monoclinic Cm space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to two equivalent Co(2), two equivalent Co(3), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Co site, Co(2) is bonded in a 11-coordinate geometry to one Co(4), two equivalent Co(1), two equivalent Co(3), one Ge(2), one Ge(4), two equivalent Ge(1), and two equivalent Ge(3) atoms. In the third Co site, Co(3) is bonded in a 10-coordinate geometry to two equivalent Co(1), two equivalent Co(2), one Ge(2), one Ge(4), two equivalent Ge(1), and two equivalent Ge(3) atoms. In the fourth Co site, Co(4) is bonded in a 7-coordinate geometry to one Co(2), one Ge(1), two equivalent Ge(2), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to one Co(4), two equivalent Co(2), two equivalent Co(3), one Ge(2), and one Ge(3) atom. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to one Co(2), one Co(3), two equivalent Co(1), two equivalent Co(4), and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Co(1), two equivalent Co(2), two equivalent Co(3), two equivalent Co(4), and one Ge(1) atom. In the fourth Ge site, Ge(4) is bonded to one Co(2), one Co(3), and two equivalent Co(4) atoms to form distorted corner-sharing GeCo4 tetrahedra. is represented by the CIF file [CIF]
