Materials Data on U8TiS17 by Materials Project
Abstract
U8TiS17 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent U+3.75+ sites. In the first U+3.75+ site, U+3.75+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of U–S bond distances ranging from 2.75–2.90 Å. In the second U+3.75+ site, U+3.75+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of U–S bond distances ranging from 2.72–2.80 Å. In the third U+3.75+ site, U+3.75+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of U–S bond distances ranging from 2.68–3.01 Å. Ti4+ is bonded in an octahedral geometry to six S2- atoms. There are two shorter (2.37 Å) and four longer (2.44 Å) Ti–S bond lengths. There are seven inequivalent S2- sites. In the first S2- site, S2- is bonded to four U+3.75+ atoms to form distorted SU4 trigonal pyramids that share corners with two equivalent SU6 octahedra, corners with six equivalent SU3Ti tetrahedra, corners with two equivalent SU3Ti trigonal pyramids, edges with two equivalent SU3Ti tetrahedra, and an edgeedge with one SU4 trigonal pyramid. The corner-sharing octahedral tilt angles are 37°. In the second S2- site, S2- ismore »
