Mo3Zn3O8 is Spinel-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Mo+3.33+ sites. In the first Mo+3.33+ site, Mo+3.33+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six ZnO4 tetrahedra, edges with two ZnO6 octahedra, and edges with four equivalent MoO6 octahedra. There are four shorter (2.15 Å) and two longer (2.19 Å) Mo–O bond lengths. In the second Mo+3.33+ site, Mo+3.33+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six ZnO4 tetrahedra, edges with two ZnO6 octahedra, and edges with four MoO6 octahedra. There are a spread of Mo–O bond distances ranging from 2.12–2.15 Å. There are four inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with six MoO6 octahedra. There are four shorter (2.13 Å) and two longer (2.23 Å) Zn–O bond lengths. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and corners with nine MoO6 octahedra. The corner-sharing octahedra tilt angles range from 51–61°. There are a spread of Zn–O bond distances ranging from 2.00–2.09 Å. In the third Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three equivalent ZnO6 octahedra and corners with nine MoO6 octahedra. The corner-sharing octahedra tilt angles range from 54–62°. There are a spread of Zn–O bond distances ranging from 2.00–2.08 Å. In the fourth Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent ZnO4 tetrahedra and edges with six MoO6 octahedra. There are four shorter (2.11 Å) and two longer (2.22 Å) Zn–O bond lengths. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to three Mo+3.33+ and one Zn2+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mo+3.33+ and two Zn2+ atoms. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to two Mo+3.33+ and two Zn2+ atoms. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Mo+3.33+ and one Zn2+ atom. In the fifth O2- site, O2- is bonded in a rectangular see-saw-like geometry to two Mo+3.33+ and two Zn2+ atoms. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to two equivalent Mo+3.33+ and two Zn2+ atoms.
