Materials Data on Sm2P3Pt4 by Materials Project
Sm2Pt4P3 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. there are two inequivalent Sm+2.50+ sites. In the first Sm+2.50+ site, Sm+2.50+ is bonded in a 6-coordinate geometry to nine Pt1- and six P+0.33- atoms. There are a spread of Sm–Pt bond distances ranging from 3.20–3.35 Å. All Sm–P bond lengths are 3.12 Å. In the second Sm+2.50+ site, Sm+2.50+ is bonded in a 6-coordinate geometry to nine Pt1- and six P+0.33- atoms. There are a spread of Sm–Pt bond distances ranging from 3.20–3.35 Å. All Sm–P bond lengths are 3.12 Å. There are two inequivalent Pt1- sites. In the first Pt1- site, Pt1- is bonded in a 3-coordinate geometry to five Sm+2.50+ and three P+0.33- atoms. There are two shorter (2.32 Å) and one longer (2.33 Å) Pt–P bond lengths. In the second Pt1- site, Pt1- is bonded in a 12-coordinate geometry to four equivalent Sm+2.50+ and four P+0.33- atoms. There are two shorter (2.51 Å) and two longer (2.52 Å) Pt–P bond lengths. There are four inequivalent P+0.33- sites. In the first P+0.33- site, P+0.33- is bonded in a 9-coordinate geometry to four equivalent Sm+2.50+ and five Pt1- atoms. In the second P+0.33- site, P+0.33- is bonded in a 9-coordinate geometry to four equivalent Sm+2.50+ and five Pt1- atoms. There are a spread of P–Pt bond distances ranging from 2.33–2.52 Å. In the third P+0.33- site, P+0.33- is bonded in a 8-coordinate geometry to four Sm+2.50+ and four equivalent Pt1- atoms. In the fourth P+0.33- site, P+0.33- is bonded in a 9-coordinate geometry to four equivalent Sm+2.50+ and five Pt1- atoms. All P–Sm bond lengths are 3.12 Å. The P–Pt bond length is 2.33 Å.
