NaMo2Mn2H3O10 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with four equivalent MnO6 octahedra and corners with six equivalent MoO4 tetrahedra. The corner-sharing octahedral tilt angles are 68°. There are a spread of Na–O bond distances ranging from 2.54–2.58 Å. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent NaO6 octahedra and corners with four equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 48–71°. There are a spread of Mo–O bond distances ranging from 1.77–1.85 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent NaO6 octahedra, corners with four equivalent MoO4 tetrahedra, and edges with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 68°. There are a spread of Mn–O bond distances ranging from 2.19–2.24 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+ and one Mo6+ atom. In the second O2- site, O2- is bonded to two equivalent Mn2+ and two H1+ atoms to form distorted corner-sharing OMn2H2 tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mo6+ and two equivalent Mn2+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Na1+, one Mo6+, and one Mn2+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to one Na1+, one Mo6+, and one Mn2+ atom.
