Materials Data on YOs2 by Materials Project
YOs2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y3+ is bonded in a 12-coordinate geometry to twelve Os+1.50- atoms. There are nine shorter (3.13 Å) and three longer (3.15 Å) Y–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 Y3+ and six equivalent Os+1.50- atoms to form a mixture of face, edge, and corner-sharing OsY6Os6 cuboctahedra. All Os–Os bond lengths are 2.73 Å. In the second Os+1.50- site, Os+1.50- is bonded to six equivalent Y3+ and six Os+1.50- atoms to form a mixture of face, edge, and corner-sharing OsY6Os6 cuboctahedra. There are two shorter (2.58 Å) and two longer (2.76 Å) Os–Os bond lengths.
