资源简介：
Mg2Pm is Cubic Laves structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to six equivalent Mg and six equivalent Pm atoms to form a mixture of edge, face, and corner-sharing MgPm6Mg6 cuboctahedra. All Mg–Mg bond lengths are 3.05 Å. All Mg–Pm bond lengths are 3.58 Å. In the second Mg site, Mg is bonded to six Mg and six equivalent Pm atoms to form a mixture of edge, face, and corner-sharing MgPm6Mg6 cuboctahedra. All Mg–Mg bond lengths are 3.06 Å. There are four shorter (3.58 Å) and two longer (3.59 Å) Mg–Pm bond lengths. Pm is bonded in a 12-coordinate geometry to twelve Mg and four equivalent Pm atoms. All Pm–Pm bond lengths are 3.74 Å.
