Materials Data on UMnO4 by Materials Project
MnUO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with eight equivalent MnO6 octahedra and edges with two equivalent UO6 octahedra. The corner-sharing octahedra tilt angles range from 47–60°. There are a spread of U–O bond distances ranging from 1.98–2.18 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with eight equivalent UO6 octahedra and edges with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–60°. There are two shorter (2.15 Å) and four longer (2.24 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent U6+ and one Mn2+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one U6+ and two equivalent Mn2+ atoms.
