Abstract

Sm26Co11Ga6 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are six inequivalent Sm sites. In the first Sm site, Sm is bonded in a 6-coordinate geometry to three Co and three Ga atoms. There are a spread of Sm–Co bond distances ranging from 2.68–2.98 Å. There are a spread of Sm–Ga bond distances ranging from 3.06–3.43 Å. In the second Sm site, Sm is bonded in a 4-coordinate geometry to four Co atoms. There are two shorter (2.80 Å) and two longer (3.03 Å) Sm–Co bond lengths. In the third Sm site, Sm is bonded in a 6-coordinate geometry to five Co and one Ga atom. There are a spread of Sm–Co bond distances ranging from 2.90–3.48 Å. The Sm–Ga bond length is 3.29 Å. In the fourth Sm site, Sm is bonded in a 4-coordinate geometry to two equivalent Co and four Ga atoms. Both Sm–Co bond lengths are 2.91 Å. There are a spread of Sm–Ga bond distances ranging from 3.14–3.67 Å. In the fifth Sm site, Sm is bonded in a 6-coordinate geometry to four Co and two equivalent Ga atoms.
