Materials Data on U2SiO10 by Materials Project
Abstract
U2SiO10 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. U is bonded to seven O atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent SiO4 tetrahedra, edges with two equivalent UO7 pentagonal bipyramids, and an edgeedge with one SiO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.83–2.47 Å. Si is bonded to four equivalent O atoms to form SiO4 tetrahedra that share corners with four equivalent UO7 pentagonal bipyramids and edges with two equivalent UO7 pentagonal bipyramids. All Si–O bond lengths are 1.64 Å. There are three inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to two equivalent U and one Si atom. In the second O site, O is bonded in a single-bond geometry to one U atom. In the third O site, O is bonded in a single-bond geometry to one U atom.
