Materials Data on ZrOs2 by Materials Project
ZrOs2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Zr4+ is bonded in a 12-coordinate geometry to twelve Os2- atoms. There are a spread of Zr–Os bond distances ranging from 3.06–3.09 Å. There are two inequivalent Os2- sites. In the first Os2- site, Os2- is bonded to six equivalent Zr4+ and six equivalent Os2- atoms to form a mixture of face, edge, and corner-sharing OsZr6Os6 cuboctahedra. All Os–Os bond lengths are 2.66 Å. In the second Os2- site, Os2- is bonded to six equivalent Zr4+ and six Os2- atoms to form a mixture of face, edge, and corner-sharing OsZr6Os6 cuboctahedra. There are two shorter (2.53 Å) and two longer (2.72 Å) Os–Os bond lengths.
