Materials Data on U2AsSe by Materials Project
Abstract
U2AsSe is Caswellsilverite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent U sites. In the first U site, U is bonded to three As and three Se atoms to form a mixture of edge and corner-sharing UAs3Se3 octahedra. The corner-sharing octahedra tilt angles range from 1–2°. There are one shorter (2.88 Å) and two longer (2.89 Å) U–As bond lengths. There are two shorter (2.89 Å) and one longer (2.90 Å) U–Se bond lengths. In the second U site, U is bonded to three As and three Se atoms to form a mixture of edge and corner-sharing UAs3Se3 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are two shorter (2.88 Å) and one longer (2.89 Å) U–As bond lengths. There are two shorter (2.89 Å) and one longer (2.90 Å) U–Se bond lengths. In the third U site, U is bonded to three As and three Se atoms to form a mixture of edge and corner-sharing UAs3Se3 octahedra. The corner-sharing octahedra tilt angles range from 1–2°. There are one shorter (2.88 Å) and two longer (2.89 Å) U–As bond lengths. There are two shorter (2.89 Å) and one longermore »
