Zr4GeSb7 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded in a 8-coordinate geometry to eight Sb+2.86- atoms. There are a spread of Zr–Sb bond distances ranging from 2.95–3.21 Å. In the second Zr4+ site, Zr4+ is bonded in a 8-coordinate geometry to eight Sb+2.86- atoms. There are a spread of Zr–Sb bond distances ranging from 3.01–3.33 Å. In the third Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to seven Sb+2.86- atoms. There are a spread of Zr–Sb bond distances ranging from 2.97–3.13 Å. In the fourth Zr4+ site, Zr4+ is bonded in a 9-coordinate geometry to nine Sb+2.86- atoms. There are a spread of Zr–Sb bond distances ranging from 3.00–3.32 Å. Ge4+ is bonded in a distorted rectangular see-saw-like geometry to four Sb+2.86- atoms. There are two shorter (2.82 Å) and two longer (3.06 Å) Ge–Sb bond lengths. There are seven inequivalent Sb+2.86- sites. In the first Sb+2.86- site, Sb+2.86- is bonded in a 7-coordinate geometry to five Zr4+ and two equivalent Sb+2.86- atoms. Both Sb–Sb bond lengths are 3.14 Å. In the second Sb+2.86- site, Sb+2.86- is bonded in a 5-coordinate geometry to five Zr4+ atoms. In the third Sb+2.86- site, Sb+2.86- is bonded in a 7-coordinate geometry to five Zr4+ and two equivalent Sb+2.86- atoms. Both Sb–Sb bond lengths are 3.15 Å. In the fourth Sb+2.86- site, Sb+2.86- is bonded in a 7-coordinate geometry to five Zr4+ and two equivalent Ge4+ atoms. In the fifth Sb+2.86- site, Sb+2.86- is bonded in a 8-coordinate geometry to four Zr4+ and four Sb+2.86- atoms. Both Sb–Sb bond lengths are 2.94 Å. In the sixth Sb+2.86- site, Sb+2.86- is bonded in a 6-coordinate geometry to four Zr4+ and two equivalent Ge4+ atoms. In the seventh Sb+2.86- site, Sb+2.86- is bonded in a 8-coordinate geometry to four Zr4+ and four Sb+2.86- atoms.
