Materials Data on GdOs2 by Materials Project
GdOs2 is Hexagonal Laves structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd3+ is bonded in a 12-coordinate geometry to twelve Os+1.50- atoms. There are a spread of Gd–Os bond distances ranging from 3.13–3.19 Å. There are three inequivalent Os+1.50- sites. In the first Os+1.50- site, Os+1.50- is bonded to six equivalent Gd3+ and six Os+1.50- atoms to form a mixture of corner, edge, and face-sharing OsGd6Os6 cuboctahedra. There are four shorter (2.73 Å) and two longer (2.74 Å) Os–Os bond lengths. In the second Os+1.50- site, Os+1.50- is bonded to six equivalent Gd3+ and six Os+1.50- atoms to form a mixture of corner, edge, and face-sharing OsGd6Os6 cuboctahedra. There are a spread of Os–Os bond distances ranging from 2.59–2.76 Å. In the third Os+1.50- site, Os+1.50- is bonded to six equivalent Gd3+ and six Os+1.50- atoms to form a mixture of corner, edge, and face-sharing OsGd6Os6 cuboctahedra.
