Materials Data on La9Sb16Br3 by Materials Project
La9Sb16Br3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of La–Sb bond distances ranging from 3.29–3.44 Å. In the second La3+ site, La3+ is bonded in a 3-coordinate geometry to six Sb+1.50- and three equivalent Br1- atoms. There are a spread of La–Sb bond distances ranging from 3.40–3.54 Å. There are two shorter (3.03 Å) and one longer (3.14 Å) La–Br bond lengths. In the third La3+ site, La3+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of La–Sb bond distances ranging from 3.32–3.47 Å. There are six inequivalent Sb+1.50- sites. In the first Sb+1.50- site, Sb+1.50- is bonded to six equivalent La3+ atoms to form distorted face-sharing SbLa6 pentagonal pyramids. In the second Sb+1.50- site, Sb+1.50- is bonded in a 7-coordinate geometry to five La3+ and two equivalent Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.07 Å. In the third Sb+1.50- site, Sb+1.50- is bonded in a 7-coordinate geometry to five La3+ and two equivalent Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.14 Å. In the fourth Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four La3+ and four Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.12 Å. In the fifth Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four La3+ and four Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.16 Å. In the sixth Sb+1.50- site, Sb+1.50- is bonded in a 8-coordinate geometry to four La3+ and four Sb+1.50- atoms. Br1- is bonded in a trigonal non-coplanar geometry to three equivalent La3+ atoms.
