Materials Data on Np(WO4)2 by Materials Project
Np(WO4)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Np4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Np–O bond distances ranging from 2.30–2.41 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of W–O bond distances ranging from 1.81–1.84 Å. In the second W6+ site, W6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.81 Å) and two longer (1.82 Å) W–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to one Np4+ and one W6+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Np4+ and one W6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Np4+ and one W6+ atom.
