Title: Materials Data on LaSi2Pt by Materials Project

Abstract

LaPtSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. La2+ is bonded in a 4-coordinate geometry to four equivalent Pt2- atoms. All La–Pt bond lengths are 3.31 Å. Pt2- is bonded in a 5-coordinate geometry to four equivalent La2+ and five Si atoms. There are a spread of Pt–Si bond distances ranging from 2.44–2.48 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded to four equivalent Pt2- atoms to form a mixture of edge and corner-sharing SiPt4 tetrahedra. In the second Si site, Si is bonded in a distorted trigonal planar geometry to one Pt2- and two equivalent Si atoms. Both Si–Si bond lengths are 2.47 Å.
