Materials Data on LuOs2 by Materials Project
LuOs2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu3+ is bonded in a 12-coordinate geometry to twelve Os+1.50- atoms. There are nine shorter (3.11 Å) and three longer (3.12 Å) Lu–Os bond lengths. There are two inequivalent Os+1.50- sites. In the first Os+1.50- site, Os+1.50- is bonded to six equivalent Lu3+ and six equivalent Os+1.50- atoms to form a mixture of corner, edge, and face-sharing OsLu6Os6 cuboctahedra. All Os–Os bond lengths are 2.70 Å. In the second Os+1.50- site, Os+1.50- is bonded to six equivalent Lu3+ and six Os+1.50- atoms to form a mixture of corner, edge, and face-sharing OsLu6Os6 cuboctahedra. There are two shorter (2.55 Å) and two longer (2.75 Å) Os–Os bond lengths.
