Materials Data on Np(SiPt)2 by Materials Project
Np(PtSi)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Np4+ is bonded in a 8-coordinate geometry to eight Pt2- atoms. There are four shorter (3.22 Å) and four longer (3.28 Å) Np–Pt bond lengths. There are two inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a 5-coordinate geometry to four equivalent Np4+ and five Si atoms. There are one shorter (2.40 Å) and four longer (2.43 Å) Pt–Si bond lengths. In the second Pt2- site, Pt2- is bonded to four equivalent Np4+ and four equivalent Si atoms to form a mixture of distorted edge and face-sharing PtNp4Si4 tetrahedra. All Pt–Si bond lengths are 2.50 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 5-coordinate geometry to five Pt2- atoms. In the second Si site, Si is bonded to four equivalent Pt2- atoms to form a mixture of edge and corner-sharing SiPt4 tetrahedra.
