Materials Data on CeGa4Os by Materials Project
CeOsGa4 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 10-coordinate geometry to twelve Ga atoms. There are a spread of Ce–Ga bond distances ranging from 3.05–3.51 Å. In the second Ce site, Ce is bonded in a 12-coordinate geometry to four equivalent Os and twelve Ga atoms. All Ce–Os bond lengths are 3.48 Å. There are a spread of Ce–Ga bond distances ranging from 2.99–3.45 Å. There are two inequivalent Os sites. In the first Os site, Os is bonded in a 12-coordinate geometry to eight Ga atoms. There are a spread of Os–Ga bond distances ranging from 2.59–2.67 Å. In the second Os site, Os is bonded in a 8-coordinate geometry to two equivalent Ce and eight Ga atoms. There are a spread of Os–Ga bond distances ranging from 2.58–2.70 Å. There are six inequivalent Ga sites. In the first Ga site, Ga is bonded to six Ce and six Ga atoms to form face-sharing GaCe6Ga6 cuboctahedra. There are two shorter (2.78 Å) and four longer (2.80 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Ce, two equivalent Os, and six Ga atoms. There are four shorter (2.70 Å) and two longer (2.86 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 10-coordinate geometry to two equivalent Ce, three Os, and five Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.77–2.81 Å. In the fourth Ga site, Ga is bonded in a 5-coordinate geometry to four Ce, two equivalent Os, and one Ga atom. In the fifth Ga site, Ga is bonded in a 2-coordinate geometry to three Ce, two Os, and four Ga atoms. The Ga–Ga bond length is 2.77 Å. In the sixth Ga site, Ga is bonded in a 10-coordinate geometry to two Ce, two equivalent Os, and six Ga atoms. The Ga–Ga bond length is 2.80 Å.
