Materials Data on DyPPt by Materials Project

DyPtP is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Dy3+ is bonded to six equivalent Pt2- and six equivalent P1- atoms to form a mixture of edge and face-sharing DyP6Pt6 cuboctahedra. All Dy–Pt bond lengths are 3.08 Å. All Dy–P bond lengths are 3.08 Å. Pt2- is bonded in a 9-coordinate geometry to six equivalent Dy3+ and three equivalent P1- atoms. All Pt–P bond lengths are 2.39 Å. P1- is bonded in a 9-coordinate geometry to six equivalent Dy3+ and three equivalent Pt2- atoms.

Materials Data on Dy(PPt4)2 by Materials Project

Dy(Pt4P)2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one Dy(Pt4P)2 sheet oriented in the (0, 0, 1) direction. Dy3+ is bonded to twelve Pt+0.62- atoms to form distorted face-sharing DyPt12 cuboctahedra. There are a spread of Dy–Pt bond distances ranging from 3.06–3.30 Å. There are four inequivalent Pt+0.62- sites. In the first Pt+0.62- site, Pt+0.62- is bonded in a 1-coordinate geometry to two equivalent Dy3+ and one P1+ atom. The Pt–P bond length is 2.23 Å. In the second Pt+0.62- site, Pt+0.62- is bonded in a distorted single-bond geometry to two equivalent Dy3+ and one P1+ atom. The Pt–P bond length is 2.29 Å. In the third Pt+0.62- site, Pt+0.62- is bonded in a distorted single-bond geometry to one Dy3+ and one P1+ atom. The Pt–P bond length is 2.33 Å. In the fourth Pt+0.62- site, Pt+0.62- is bonded in a distorted bent 120 degrees geometry to one Dy3+ and two equivalent P1+ atoms. Both Pt–P bond lengths are 2.36 Å. P1+ is bonded in a 5-coordinate geometry to five Pt+0.62- atoms.
