Materials Data on MgPt5 by Materials Project

MgPt5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mg2+ is bonded to twelve Pt+0.40- atoms to form a mixture of edge and face-sharing MgPt12 cuboctahedra. All Mg–Pt bond lengths are 2.82 Å. There are two inequivalent Pt+0.40- sites. In the first Pt+0.40- site, Pt+0.40- is bonded in a distorted water-like geometry to two equivalent Mg2+ atoms. In the second Pt+0.40- site, Pt+0.40- is bonded in a distorted trigonal planar geometry to three equivalent Mg2+ atoms.

MgPt₅结晶于六方晶系P-62m空间群。其结构为三维结构。Mg²⁺与12个Pt⁺⁰·⁴⁰⁻原子键合，形成边共享与面共享的MgPt₁₂立方八面体（cuboctahedra）混合物。所有Mg–Pt键的键长（bond length）均为2.82埃。存在两种不等价位点（inequivalent site）的Pt⁺⁰·⁴⁰⁻原子。在第一个Pt⁺⁰·⁴⁰⁻位点中，Pt⁺⁰·⁴⁰⁻以扭曲的类水几何构型（water-like geometry）与两个等价的Mg²⁺原子键合。在第二个Pt⁺⁰·⁴⁰⁻位点中，Pt⁺⁰·⁴⁰⁻以扭曲的三角平面几何构型（trigonal planar geometry）与三个等价的Mg²⁺原子键合。
