The material structure described by Pt5TlSi crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to two equivalent Tl(1) and two equivalent Si(1) atoms. In the second Pt site, Pt(2) is bonded in a square co-planar geometry to four equivalent Tl(1) atoms. Tl(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form a mixture of corner and face-sharing TlPt12 cuboctahedra. Si(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms. is represented by the CIF card [CIF]
