Abstract

Sm2CuGa3 is Tungsten boride-derived structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to three equivalent Cu and nine Ga atoms. All Sm–Cu bond lengths are 2.97 Å. There are a spread of Sm–Ga bond distances ranging from 3.04–3.45 Å. In the second Sm site, Sm is bonded in a 12-coordinate geometry to three equivalent Cu and nine Ga atoms. All Sm–Cu bond lengths are 3.24 Å. There are six shorter (3.03 Å) and three longer (3.44 Å) Sm–Ga bond lengths. Cu is bonded in a 10-coordinate geometry to six Sm and four Ga atoms. There are three shorter (2.58 Å) and one longer (3.16 Å) Cu–Ga bond lengths. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to six Sm and three equivalent Cu atoms. In the second Ga site, Ga is bonded in a 9-coordinate geometry to six Sm and three equivalent Ga atoms. All Ga–Ga bond lengths are 2.64 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to six Sm, onemore » Cu, and three equivalent Ga atoms.« less
