Materials Data on Ce2Ga7Pd by Materials Project
Ce2PdGa7 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 8-coordinate geometry to four equivalent Pd and twelve Ga atoms. All Ce–Pd bond lengths are 3.37 Å. There are a spread of Ce–Ga bond distances ranging from 3.28–3.39 Å. In the second Ce site, Ce is bonded in a 12-coordinate geometry to sixteen Ga atoms. There are a spread of Ce–Ga bond distances ranging from 3.28–3.48 Å. Pd is bonded in a 5-coordinate geometry to four equivalent Ce and five Ga atoms. There are one shorter (2.44 Å) and four longer (2.51 Å) Pd–Ga bond lengths. There are five inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted bent 120 degrees geometry to four Ce, two equivalent Pd, and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.63 Å. In the second Ga site, Ga is bonded in a 12-coordinate geometry to four Ce and four Ga atoms. There are two shorter (2.59 Å) and two longer (2.65 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Ce and five Ga atoms. The Ga–Ga bond length is 2.44 Å. In the fourth Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Ce and five Ga atoms. In the fifth Ga site, Ga is bonded in a distorted single-bond geometry to four equivalent Ce, one Pd, and four equivalent Ga atoms.
