The crystal structure described by Li4Pt3Si crystallizes in the trigonal R32 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 13-coordinate geometry to six equivalent Li(2), three equivalent Pt(1), three equivalent Pt(2), and one Si(1) atom. In the second Li site, Li(2) is bonded in a 13-coordinate geometry to two equivalent Li(1), four equivalent Li(2), three equivalent Pt(1), three equivalent Pt(2), and one Si(1) atom. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 8-coordinate geometry to two equivalent Li(1), six equivalent Li(2), and two equivalent Si(1) atoms. In the second Pt site, Pt(1) is bonded in a 10-coordinate geometry to two equivalent Li(1), six equivalent Li(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to one Li(1), three equivalent Li(2), three equivalent Pt(1), and three equivalent Pt(2) atoms. is represented by the CIF file [CIF]
