Materials Data on Na2U(MoO4)3 by Materials Project

Abstract

Na2U(MoO4)3 is Zircon-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.52–2.59 Å. U4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of U–O bond distances ranging from 2.33–2.41 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.76–1.84 Å. In the second Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.77 Å) and two longer (1.86 Å) Mo–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one U4+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one U4+, and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one U4+, and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one U4+, and one Mo6+ atom.
