Materials Data on Er5(In2Pt)2 by Materials Project

Er5(PtIn2)2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded in a 8-coordinate geometry to two equivalent Pt and six In atoms. Both Er–Pt bond lengths are 2.81 Å. There are a spread of Er–In bond distances ranging from 3.22–3.39 Å. In the second Er site, Er is bonded in a 10-coordinate geometry to four equivalent Pt and six In atoms. There are two shorter (2.94 Å) and two longer (2.95 Å) Er–Pt bond lengths. There are a spread of Er–In bond distances ranging from 3.32–3.42 Å. In the third Er site, Er is bonded in a distorted body-centered cubic geometry to eight In atoms. There are four shorter (3.22 Å) and four longer (3.32 Å) Er–In bond lengths. Pt is bonded in a 9-coordinate geometry to six Er and three In atoms. There are a spread of Pt–In bond distances ranging from 2.91–3.37 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 1-coordinate geometry to eight Er, two equivalent Pt, and one In atom. The In–In bond length is 3.36 Å. In the second In site, In is bonded in a 9-coordinate geometry to eight Er, one Pt, and one In atom.
