Materials Data on MgPt5 by Materials Project
MgPt5 crystallizes in the monoclinic Cm space group. The structure is two-dimensional and consists of one MgPt5 sheet oriented in the (0, 0, 1) direction. Mg2+ is bonded in a distorted q6 geometry to ten Pt+0.40- atoms. There are a spread of Mg–Pt bond distances ranging from 2.73–2.84 Å. There are five inequivalent Pt+0.40- sites. In the first Pt+0.40- site, Pt+0.40- is bonded to two equivalent Mg2+ atoms to form distorted PtMg2 cuboctahedra that share corners with six PtMg2 cuboctahedra and an edgeedge with one PtMg3 cuboctahedra. In the second Pt+0.40- site, Pt+0.40- is bonded in a 12-coordinate geometry to two equivalent Mg2+ atoms. In the third Pt+0.40- site, Pt+0.40- is bonded in a distorted single-bond geometry to one Mg2+ atom. In the fourth Pt+0.40- site, Pt+0.40- is bonded in a 12-coordinate geometry to two equivalent Mg2+ atoms. In the fifth Pt+0.40- site, Pt+0.40- is bonded to three equivalent Mg2+ atoms to form a mixture of distorted edge and corner-sharing PtMg3 cuboctahedra.
