Abstract
NpO5I crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Np5+ is bonded to seven O2- atoms to form distorted corner-sharing NpO7 pentagonal bipyramids. There are a spread of Np–O bond distances ranging from 1.87–2.58 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Np5+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Np5+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Np5+ and one I5+ atom. The O–I bond length is 1.83 Å. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Np5+ and one I5+ atom. The O–I bond length is 1.83 Å. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Np5+ and one I5+ atom. The O–I bond length is 1.83 Å. I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
