Title: Materials Data on Sm2MgCu2 by Materials Project

Abstract

Sm2Cu2Mg crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded to eight equivalent Sm and four equivalent Cu atoms to form a mixture of distorted corner and face-sharing MgSm8Cu4 cuboctahedra. All Mg–Sm bond lengths are 3.42 Å. All Mg–Cu bond lengths are 3.13 Å. Sm is bonded in a 6-coordinate geometry to four equivalent Mg and six equivalent Cu atoms. There are two shorter (2.92 Å) and four longer (3.00 Å) Sm–Cu bond lengths. Cu is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Sm, and one Cu atom. The Cu–Cu bond length is 2.59 Å.
