The compound described by Ti4Co7Ge6 crystallizes in the cubic Im-3m space group. Ti(1) is bonded to six equivalent Co(2) and six equivalent Ge(1) atoms to form TiCo6Ge6 cuboctahedra that share corners with twelve equivalent Ti(1)Co6Ge6 cuboctahedra, faces with six equivalent Ti(1)Co6Ge6 cuboctahedra, and faces with two equivalent Co(1)Ge6 octahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent Ge(1) atoms to form CoGe6 octahedra that share faces with eight equivalent Ti(1)Co6Ge6 cuboctahedra. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ti(1), one Co(1), and four equivalent Co(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
