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.
