Materials Data on Sm(SiPt)2 by Materials Project
SmPt2Si2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm2+ is bonded in a 8-coordinate geometry to eight Si4- atoms. There are four shorter (3.21 Å) and four longer (3.24 Å) Sm–Si bond lengths. There are two inequivalent Pt3+ sites. In the first Pt3+ site, Pt3+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are one shorter (2.42 Å) and four longer (2.44 Å) Pt–Si bond lengths. In the second Pt3+ site, Pt3+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing PtSi4 tetrahedra. All Pt–Si bond lengths are 2.50 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 9-coordinate geometry to four equivalent Sm2+ and five Pt3+ atoms. In the second Si4- site, Si4- is bonded in a 4-coordinate geometry to four equivalent Sm2+ and four equivalent Pt3+ atoms.
