The material described by MgUO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with eight equivalent U(1)O6 octahedra and edges with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-64°. 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 Mg(1)O6 octahedra and edges with two equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-64°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent U(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Mg(1) and one U(1) atom. is represented by the CIF file [CIF]
