Materials Data on Lu2SnAu2 by Materials Project
Lu2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Lu is bonded in a 8-coordinate geometry to six Au and two equivalent Sn atoms. There are two shorter (2.98 Å) and four longer (2.99 Å) Lu–Au bond lengths. Both Lu–Sn bond lengths are 3.09 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 6-coordinate geometry to six equivalent Lu atoms. In the second Au site, Au is bonded in a 6-coordinate geometry to six equivalent Lu atoms. Sn is bonded in a rectangular see-saw-like geometry to four equivalent Lu atoms.
