Mg Tl Tl Pt
MgPtTl2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgPtTl2 clusters. Mg(1) is bonded in a 3-coordinate geometry to one Pt(1) and two equivalent Tl(1) atoms. The Mg(1)-Pt(1) bond length is 1.28 Å. Both Mg(1)-Tl(1) bond lengths are 1.39 Å. Pt(1) is bonded in a 3-coordinate geometry to one Mg(1) and two equivalent Tl(1) atoms. Both Pt(1)-Tl(1) bond lengths are 1.39 Å. Tl(1) is bonded in a 3-coordinate geometry to one Mg(1), one Pt(1), and one Tl(1) atom. The Tl(1)-Tl(1) bond length is 1.28 Å.
