Materials Data on ErInAu by Materials Project

ErAuIn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Er is bonded in a 11-coordinate geometry to five Au and six equivalent In atoms. There are four shorter (3.08 Å) and one longer (3.12 Å) Er–Au bond lengths. There are two shorter (3.26 Å) and four longer (3.40 Å) Er–In bond lengths. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent In atoms. All Au–In bond lengths are 2.84 Å. In the second Au site, Au is bonded in a 9-coordinate geometry to six equivalent Er and three equivalent In atoms. All Au–In bond lengths are 2.89 Å. In is bonded in a 4-coordinate geometry to six equivalent Er and four Au atoms.

Materials Data on Er2InAu2 by Materials Project

Er2Au2In crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Er is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent In atoms. There are two shorter (2.91 Å) and four longer (3.02 Å) Er–Au bond lengths. All Er–In bond lengths are 3.48 Å. Au is bonded in a 9-coordinate geometry to six equivalent Er, one Au, and two equivalent In atoms. The Au–Au bond length is 2.89 Å. Both Au–In bond lengths are 3.14 Å. In is bonded to eight equivalent Er and four equivalent Au atoms to form a mixture of distorted face and corner-sharing InEr8Au4 cuboctahedra.
