Title: Materials Data on UAs2 by Materials Project

Abstract

UAs2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. U6+ is bonded in a 9-coordinate geometry to nine As3- atoms. There are a spread of U–As bond distances ranging from 2.87–3.03 Å. There are two inequivalent As3- sites. In the first As3- site, As3- is bonded in a 8-coordinate geometry to four equivalent U6+ and four equivalent As3- atoms. All As–As bond lengths are 2.80 Å. In the second As3- site, As3- is bonded to five equivalent U6+ atoms to form a mixture of distorted edge and corner-sharing AsU5 square pyramids.
