MgMoOs(PbO3)2 crystallizes in the orthorhombic Immm space group. Mg(1) is bonded in a distorted square co-planar geometry to two equivalent Pb(1) and four equivalent O(1) atoms. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MoO6 octahedra that share corners with six equivalent Os(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Os(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form OsO6 octahedra that share corners with six equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Pb(1) is bonded in a 5-coordinate geometry to one Mg(1) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Mg(1), one Mo(1), one Os(1), and two equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a linear geometry to one Mo(1) and one Os(1) atom.
