Abstract

Er11Cd45 is Bergman Structure: Mg32(Al,Zn)49 Bergman-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are five inequivalent Er sites. In the first Er site, Er is bonded in a 8-coordinate geometry to fourteen Cd atoms. There are a spread of Er–Cd bond distances ranging from 3.13–3.39 Å. In the second Er site, Er is bonded in a 12-coordinate geometry to fourteen Cd atoms. There are a spread of Er–Cd bond distances ranging from 3.17–3.81 Å. In the third Er site, Er is bonded in a 4-coordinate geometry to sixteen Cd atoms. There are four shorter (3.25 Å) and twelve longer (3.36 Å) Er–Cd bond lengths. In the fourth Er site, Er is bonded in a 3-coordinate geometry to sixteen Cd atoms. There are a spread of Er–Cd bond distances ranging from 3.25–3.52 Å. In the fifth Er site, Er is bonded in a 10-coordinate geometry to sixteen Cd atoms. There are a spread of Er–Cd bond distances ranging from 3.13–3.66 Å. There are fourteen inequivalent Cd sites. In the first Cd site, Cd is bonded in a 9-coordinate geometry to five Er and eight Cd atoms. There are a spread of Cd–Cd bond distances ranging from 3.01–3.12 Å. In the second Cd site, Cd is bonded in a 4-coordinate geometry to four equivalent Er and twelve equivalent Cd atoms. All Cd–Cd bond lengths are 3.35 Å. In the third Cd site, Cd is bonded to three Er and nine Cd atoms to form a mixture of distorted edge, corner, and face-sharing CdEr3Cd9 cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 2.79–3.16 Å. In the fourth Cd site, Cd is bonded in a 8-coordinate geometry to four Er and four Cd atoms. There are two shorter (2.89 Å) and two longer (3.02 Å) Cd–Cd bond lengths. In the fifth Cd site, Cd is bonded to four Er and eight Cd atoms to form a mixture of distorted edge, corner, and face-sharing CdEr4Cd8 cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 2.81–3.32 Å. In the sixth Cd site, Cd is bonded in a 3-coordinate geometry to three Er and eight Cd atoms. There are a spread of Cd–Cd bond distances ranging from 2.99–3.28 Å. In the seventh Cd site, Cd is bonded in a 12-coordinate geometry to four Er and eight Cd atoms. Both Cd–Cd bond lengths are 3.21 Å. In the eighth Cd site, Cd is bonded in a 11-coordinate geometry to three equivalent Er and eight Cd atoms. There are one shorter (3.01 Å) and one longer (3.13 Å) Cd–Cd bond lengths. In the ninth Cd site, Cd is bonded in a 11-coordinate geometry to four Er and seven Cd atoms. The Cd–Cd bond length is 3.02 Å. In the tenth Cd site, Cd is bonded in a 12-coordinate geometry to three Er and nine Cd atoms.
