The crystal structure described by Ti6Ni16Ge7 crystallizes in the cubic Fm-3m space group. Ti(1) is bonded in a 12-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), and four equivalent Ge(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 13-coordinate geometry to three equivalent Ti(1), three equivalent Ni(1), three equivalent Ni(2), one Ge(2), and three equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a 6-coordinate geometry to three equivalent Ti(1), three equivalent Ni(1), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a body-centered cubic geometry to eight equivalent Ni(1) atoms. In the second Ge site, Ge(1) is bonded to four equivalent Ti(1), four equivalent Ni(1), and four equivalent Ni(2) atoms to form a mixture of distorted face and corner-sharing GeTi4Ni8 cuboctahedra. is represented by the CIF card [CIF]
