Materials Data on Eu2MnP3Pt7 by Materials Project
Abstract
Eu2MnPt7P3 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Eu+2.50+ is bonded in a 9-coordinate geometry to nine Pt2- atoms. There are a spread of Eu–Pt bond distances ranging from 3.12–3.48 Å. Mn2+ is bonded to twelve Pt2- atoms to form MnPt12 cuboctahedra that share corners with four equivalent MnPt12 cuboctahedra, faces with four equivalent MnPt12 cuboctahedra, and faces with four equivalent PtMn4Pt8 cuboctahedra. There are a spread of Mn–Pt bond distances ranging from 2.82–2.90 Å. There are four inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a 12-coordinate geometry to two equivalent Eu+2.50+, two equivalent Mn2+, six Pt2-, and two equivalent P+2.33+ atoms. There are two shorter (2.82 Å) and four longer (2.90 Å) Pt–Pt bond lengths. Both Pt–P bond lengths are 2.44 Å. In the second Pt2- site, Pt2- is bonded in a 12-coordinate geometry to two equivalent Eu+2.50+, two equivalent Mn2+, six Pt2-, and two equivalent P+2.33+ atoms. Both Pt–Pt bond lengths are 2.84 Å. Both Pt–P bond lengths are 2.43 Å. In the third Pt2- site, Pt2- is bonded in a 3-coordinate geometry to five equivalent Eu+2.50+ and three P+2.33+ atoms. All Pt–P bond lengths are 2.36 Å. Inmore »
