Materials Data on Pm3Au by Materials Project

Pm3Au crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pm is bonded in a distorted see-saw-like geometry to four equivalent Au atoms. There are two shorter (3.28 Å) and two longer (3.50 Å) Pm–Au bond lengths. Au is bonded to twelve equivalent Pm atoms to form a mixture of face and corner-sharing AuPm12 cuboctahedra.

Pm₃Au 结晶于六方晶系P6₃/mmc空间群。该晶体为三维结构。钷（Pm）以畸变跷跷板状配位几何与四个等价的金（Au）原子配位，Pm–Au键存在两组键长：2个较短键长为3.28 Å，2个较长键长为3.50 Å。金（Au）与十二个等价的钷原子配位，形成兼具面共享与角共享特征的AuPm₁₂立方八面体。
