Materials Data on EuAsPt by Materials Project
EuPtAs is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Eu3+ is bonded to six equivalent Pt2- and six equivalent As1- atoms to form a mixture of edge and face-sharing EuAs6Pt6 cuboctahedra. There are four shorter (3.26 Å) and two longer (3.30 Å) Eu–Pt bond lengths. There are four shorter (3.25 Å) and two longer (3.32 Å) Eu–As bond lengths. Pt2- is bonded in a 9-coordinate geometry to six equivalent Eu3+ and three equivalent As1- atoms. All Pt–As bond lengths are 2.49 Å. As1- is bonded in a 9-coordinate geometry to six equivalent Eu3+ and three equivalent Pt2- atoms.
