Mg Re Pt Pt
MgRePt2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgRePt2 clusters. Mg(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1) atoms. Both Mg(1)-Pt(1) bond lengths are 2.12 Å. Re(1) is bonded in a 2-coordinate geometry to two equivalent Pt(1) atoms. Both Re(1)-Pt(1) bond lengths are 2.12 Å. Pt(1) is bonded in a 2-coordinate geometry to one Mg(1) and one Re(1) atom.
