The structure described by Co5Ge7 crystallizes in the tetragonal I4mm space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(3) atoms. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to two equivalent Ge(2) and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Co(1) and four equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to four equivalent Co(2), two equivalent Ge(2), and four equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 10-coordinate geometry to one Co(1), four equivalent Co(2), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. is represented by the CIF file [CIF]
