MgZr3Tl10(MoO4)12 crystallizes in the trigonal R3 space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six MoO4 tetrahedra. All Mg–O bond lengths are 2.14 Å. There are three inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six MoO4 tetrahedra. There are three shorter (2.11 Å) and three longer (2.12 Å) Zr–O bond lengths. In the second Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six MoO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.16 Å) Zr–O bond lengths. In the third Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six MoO4 tetrahedra. There are three shorter (2.07 Å) and three longer (2.17 Å) Zr–O bond lengths. There are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 34–38°. There are a spread of Mo–O bond distances ranging from 1.75–1.86 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one MgO6 octahedra and a cornercorner with one ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 35–36°. There are a spread of Mo–O bond distances ranging from 1.76–1.87 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one MgO6 octahedra and a cornercorner with one ZrO6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of Mo–O bond distances ranging from 1.76–1.87 Å. In the fourth Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 36–39°.
