Title: Materials Data on Sm2(Al3Co)3 by Materials Project

Abstract

Sm2Co3Al9 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm is bonded in a 11-coordinate geometry to eleven Al atoms. There are a spread of Sm–Al bond distances ranging from 3.00–3.11 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 8-coordinate geometry to eight Al atoms. There are a spread of Co–Al bond distances ranging from 2.51–2.59 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to eight Al atoms. There are a spread of Co–Al bond distances ranging from 2.53–2.57 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to two equivalent Sm, two equivalent Co, and six Al atoms. All Al–Al bond lengths are 2.75 Å. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Sm, three Co, and five Al atoms. There are a spread of Al–Al bond distances ranging from 2.68–2.84 Å. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Sm, three Co, and four Al atoms. Both Al–Al bond lengths are 2.92 Å. In the fourth Almore » site, Al is bonded in a 2-coordinate geometry to two equivalent Sm, two equivalent Co, and six Al atoms. The Al–Al bond length is 2.72 Å.« less
