Materials Data on NaUH9(SeO6)2 by Materials Project
Abstract
NaUH9(SeO6)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one NaUH9(SeO6)2 sheet oriented in the (1, 0, 0) direction. Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with two equivalent UO7 pentagonal bipyramids. There are a spread of Na–O bond distances ranging from 2.27–2.71 Å. U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent NaO6 octahedra. The corner-sharing octahedra tilt angles range from 12–42°. There are a spread of U–O bond distances ranging from 1.83–2.44 Å. There are nine inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifthmore »
