The material structure described by Pt3Tl2 crystallizes in the hexagonal P6_3/mmc space group. Pt(1) is bonded in a 11-coordinate geometry to six equivalent Pt(1), one Tl(1), one Tl(2), and three equivalent Tl(3) atoms. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the second Tl site, Tl(2) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the third Tl site, Tl(3) is bonded in a distorted q6 geometry to nine equivalent Pt(1) atoms. is represented by the CIF file [CIF]
