Materials Data on U4Si3Mo by Materials Project

Abstract

U4MoSi3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. U is bonded in a 7-coordinate geometry to one U and six Si atoms. The U–U bond length is 2.59 Å. There are a spread of U–Si bond distances ranging from 2.88–3.00 Å. Mo is bonded in a 4-coordinate geometry to four equivalent Si atoms. All Mo–Si bond lengths are 2.58 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 10-coordinate geometry to eight equivalent U and two equivalent Mo atoms. In the second Si site, Si is bonded in a 10-coordinate geometry to eight equivalent U and two equivalent Si atoms. Both Si–Si bond lengths are 2.65 Å.
