Materials Data on SmCd11 by Materials Project
SmCd11 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to twenty Cd atoms. There are a spread of Sm–Cd bond distances ranging from 3.54–3.86 Å. There are six inequivalent Cd sites. In the first Cd site, Cd is bonded in a 10-coordinate geometry to one Sm and nine Cd atoms. There are four shorter (2.99 Å) and five longer (3.14 Å) Cd–Cd bond lengths. In the second Cd site, Cd is bonded in a cuboctahedral geometry to twelve Cd atoms. All Cd–Cd bond lengths are 3.14 Å. In the third Cd site, Cd is bonded in a 9-coordinate geometry to three equivalent Sm and six Cd atoms. All Cd–Cd bond lengths are 2.93 Å. In the fourth Cd site, Cd is bonded in a distorted q6 geometry to two equivalent Sm and eight Cd atoms. There are two shorter (2.92 Å) and four longer (2.99 Å) Cd–Cd bond lengths. In the fifth Cd site, Cd is bonded in a 10-coordinate geometry to one Sm and nine Cd atoms. All Cd–Cd bond lengths are 3.14 Å. In the sixth Cd site, Cd is bonded in a 10-coordinate geometry to one Sm and nine Cd atoms. The Cd–Cd bond length is 3.14 Å.
