Materials Data on DyAsPt by Materials Project
DyPtAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to six equivalent Pt2- and six equivalent As1- atoms to form a mixture of edge and face-sharing DyAs6Pt6 cuboctahedra. All Dy–Pt bond lengths are 3.24 Å. All Dy–As bond lengths are 3.07 Å. In the second Dy3+ site, Dy3+ is bonded to six equivalent Pt2- and six equivalent As1- atoms to form a mixture of edge and face-sharing DyAs6Pt6 cuboctahedra. All Dy–Pt bond lengths are 3.06 Å. All Dy–As bond lengths are 3.23 Å. Pt2- is bonded in a 9-coordinate geometry to six Dy3+ and three equivalent As1- atoms. All Pt–As bond lengths are 2.49 Å. As1- is bonded in a 9-coordinate geometry to six Dy3+ and three equivalent Pt2- atoms.
