Abstract

LiSn4(PO4)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Li1+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.10 Å. There are four inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.10–2.25 Å. In the second Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.20–2.74 Å. In the third Sn2+ site, Sn2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Sn–O bond distances ranging from 2.26–2.67 Å. In the fourth Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.24–2.60 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms.
