Materials Data on LaGa4Os by Materials Project
Abstract
LaOsGa4 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 12-coordinate geometry to four equivalent Os and twelve Ga atoms. All La–Os bond lengths are 3.54 Å. There are a spread of La–Ga bond distances ranging from 3.06–3.50 Å. In the second La site, La is bonded in a 10-coordinate geometry to twelve Ga atoms. There are a spread of La–Ga bond distances ranging from 3.10–3.54 Å. There are two inequivalent Os sites. In the first Os site, Os is bonded in a 8-coordinate geometry to eight Ga atoms. There are a spread of Os–Ga bond distances ranging from 2.62–2.69 Å. In the second Os site, Os is bonded in a 8-coordinate geometry to two equivalent La and eight Ga atoms. There are a spread of Os–Ga bond distances ranging from 2.60–2.69 Å. There are six inequivalent Ga sites. In the first Ga site, Ga is bonded in a 2-coordinate geometry to three La, two Os, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.73–2.83 Å. In the second Ga site, Ga is bonded in amore »

In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to two La, two equivalent Os, and six Ga atoms. The Ga–Ga bond length is 2.78 Å. In the fifth Ga site, Ga is bonded in a 5-coordinate geometry to four La, two equivalent Os, and one Ga atom. The Ga–Ga bond length is 2.80 Å. In the sixth Ga site, Ga is bonded to six La and six Ga atoms to form face-sharing GaLa6Ga6 cuboctahedra.},
