Materials Data on Er2InCu2 by Materials Project
Er2Cu2In crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Er is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent In atoms. There are two shorter (2.86 Å) and four longer (2.89 Å) Er–Cu bond lengths. All Er–In bond lengths are 3.34 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Er, one Cu, and two equivalent In atoms. The Cu–Cu bond length is 2.55 Å. Both Cu–In bond lengths are 3.04 Å. In is bonded to eight equivalent Er and four equivalent Cu atoms to form a mixture of corner and face-sharing InEr8Cu4 cuboctahedra.
