Abstract

UMn(MoO4)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent MnO7 pentagonal bipyramids. There are a spread of U–O bond distances ranging from 1.85–2.37 Å. There are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms.
