Abstract

Li2Pr5Sn7 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded in a 5-coordinate geometry to one Pr and five Sn atoms. The Li–Pr bond length is 3.49 Å. There are a spread of Li–Sn bond distances ranging from 2.90–3.14 Å. In the second Li site, Li is bonded in a 2-coordinate geometry to one Pr and six Sn atoms. The Li–Pr bond length is 3.38 Å. There are a spread of Li–Sn bond distances ranging from 2.79–3.46 Å. There are five inequivalent Pr sites. In the first Pr site, Pr is bonded in a 10-coordinate geometry to one Li and nine Sn atoms. There are a spread of Pr–Sn bond distances ranging from 3.28–3.64 Å. In the second Pr site, Pr is bonded in a 7-coordinate geometry to one Li and eight Sn atoms. There are a spread of Pr–Sn bond distances ranging from 3.22–3.60 Å. In the third Pr site, Pr is bonded in a 7-coordinate geometry to eight Sn atoms. There are a spread of Pr–Sn bond distances ranging from 3.25–3.60 Å. In the fourth Pr site, Pr is bonded in a 7-coordinate geometry to seven Sn atoms. There are a spread of Pr–Sn bond distances ranging from 3.18–3.43 Å. In the fifth Pr site, Pr is bonded in a 7-coordinate geometry to eight Sn atoms. There are a spread of Pr–Sn bond distances ranging from 3.19–3.86 Å. There are seven inequivalent Sn sites. In the first Sn site, Sn is bonded in a 10-coordinate geometry to one Li, six Pr, and three Sn atoms. There are a spread of Sn–Sn bond distances ranging from 3.03–3.25 Å.
