Materials Data on Er6Ga17Pd5 by Materials Project
Er6Pd5Ga17 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded to twelve Ga atoms to form distorted ErGa12 cuboctahedra that share an edgeedge with one PdEr4Ga4Pd4 cuboctahedra, an edgeedge with one GaEr4Ga4Pd4 cuboctahedra, and faces with two equivalent ErGa12 cuboctahedra. There are a spread of Er–Ga bond distances ranging from 3.16–3.22 Å. In the second Er site, Er is bonded in a 10-coordinate geometry to two equivalent Pd and twelve Ga atoms. There are one shorter (3.03 Å) and one longer (3.04 Å) Er–Pd bond lengths. There are a spread of Er–Ga bond distances ranging from 3.04–3.44 Å. In the third Er site, Er is bonded in a 12-coordinate geometry to four Pd and nine Ga atoms. There are a spread of Er–Pd bond distances ranging from 3.06–3.20 Å. There are a spread of Er–Ga bond distances ranging from 3.07–3.42 Å. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to two equivalent Er, two equivalent Pd, and six Ga atoms. Both Pd–Pd bond lengths are 2.88 Å. There are a spread of Pd–Ga bond distances ranging from 2.53–2.69 Å. In the second Pd site, Pd is bonded in a 10-coordinate geometry to two equivalent Er and eight Ga atoms. There are a spread of Pd–Ga bond distances ranging from 2.63–2.77 Å. In the third Pd site, Pd is bonded to four equivalent Er, four equivalent Pd, and four Ga atoms to form distorted PdEr4Ga4Pd4 cuboctahedra that share edges with two equivalent ErGa12 cuboctahedra and faces with two equivalent PdEr4Ga4Pd4 cuboctahedra. There are two shorter (2.63 Å) and two longer (2.64 Å) Pd–Ga bond lengths. There are nine inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to four Er, two equivalent Pd, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.58–2.72 Å. In the second Ga site, Ga is bonded in a 9-coordinate geometry to three Er, three Pd, and three equivalent Ga atoms. There are two shorter (2.63 Å) and one longer (2.70 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 10-coordinate geometry to four Er, three Pd, and three Ga atoms. There are two shorter (2.62 Å) and one longer (2.74 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 10-coordinate geometry to four Er, two equivalent Pd, and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.58–2.70 Å. In the fifth Ga site, Ga is bonded in a 1-coordinate geometry to four Er, one Pd, and four Ga atoms. The Ga–Ga bond length is 2.55 Å. In the sixth Ga site, Ga is bonded in a 1-coordinate geometry to four Er, one Pd, and four Ga atoms. The Ga–Ga bond length is 2.54 Å. In the seventh Ga site, Ga is bonded in a 1-coordinate geometry to four Er, one Pd, and four Ga atoms. In the eighth Ga site, Ga is bonded in a 1-coordinate geometry to four Er, one Pd, and four Ga atoms. In the ninth Ga site, Ga is bonded to four equivalent Er, four equivalent Pd, and four Ga atoms to form distorted GaEr4Ga4Pd4 cuboctahedra that share edges with two equivalent ErGa12 cuboctahedra and faces with two equivalent GaEr4Ga4Pd4 cuboctahedra.
