MnUO4 is Calcite-like structured and crystallizes in the orthorhombic Cmmm space group. U(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form UO6 octahedra that share corners with eight equivalent Mn(1)O6 octahedra and edges with two equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-54°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with eight equivalent U(1)O6 octahedra and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-54°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent U(1) and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent Mn(1) atoms.
