Materials Data on Si3Pt by Materials Project
PtSi3 crystallizes in the hexagonal P6_3/mmc space group. The structure is one-dimensional and consists of two PtSi3 ribbons oriented in the (0, 0, 1) direction. Pt4+ is bonded in a 6-coordinate geometry to six equivalent Si+1.33- atoms. All Pt–Si bond lengths are 2.52 Å. Si+1.33- is bonded in a 8-coordinate geometry to two equivalent Pt4+ atoms.
