Title: Materials Data on La(Al5Ru)2 by Materials Project

Abstract

La(RuAl5)2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. La is bonded in a 10-coordinate geometry to four equivalent Ru and sixteen Al atoms. All La–Ru bond lengths are 3.51 Å. There are a spread of La–Al bond distances ranging from 3.22–3.68 Å. Ru is bonded in a 10-coordinate geometry to two equivalent La and ten Al atoms. There are a spread of Ru–Al bond distances ranging from 2.59–2.79 Å. There are five inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to one La, two equivalent Ru, and two equivalent Al atoms. Both Al–Al bond lengths are 3.07 Å. In the second Al site, Al is bonded in a distorted linear geometry to two equivalent La, two equivalent Ru, and two equivalent Al atoms. Both Al–Al bond lengths are 2.90 Å. In the third Al site, Al is bonded in a 2-coordinate geometry to two equivalent La, two equivalent Ru, and two equivalent Al atoms. Both Al–Al bond lengths are 2.90 Å. In the fourth Al site, Al is bonded in a distorted bent 120 degrees geometry to two equivalent La, two equivalent Ru, and two equivalent Al atoms. Theremore » are one shorter (2.68 Å) and one longer (2.84 Å) Al–Al bond lengths. In the fifth Al site, Al is bonded in a 12-coordinate geometry to one La, two equivalent Ru, and nine Al atoms. The Al–Al bond length is 2.70 Å.« less
