Materials Data on La2SnSb4 by Materials Project
La2SnSb4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 7-coordinate geometry to seven Sb+2.50- atoms. There are a spread of La–Sb bond distances ranging from 3.18–3.46 Å. Sn4+ is bonded in a distorted linear geometry to two equivalent Sb+2.50- atoms. Both Sn–Sb bond lengths are 3.28 Å. There are two inequivalent Sb+2.50- sites. In the first Sb+2.50- site, Sb+2.50- is bonded in a 3-coordinate geometry to three equivalent La3+ atoms. In the second Sb+2.50- site, Sb+2.50- is bonded in a 4-coordinate geometry to four equivalent La3+ and one Sn4+ atom.
