Mg Tc Tc Pt
MgTc2Pt is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgTc2Pt clusters. Mg(1) is bonded in a 2-coordinate geometry to two equivalent Tc(1) atoms. Both Mg(1)-Tc(1) bond lengths are 1.44 Å. Tc(1) is bonded in a distorted single-bond geometry to one Mg(1) and one Pt(1) atom. The Tc(1)-Pt(1) bond length is 0.60 Å. Pt(1) is bonded in a 2-coordinate geometry to two equivalent Tc(1) atoms.
