Materials Data on KPt3 by Materials Project

KPt3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K is bonded to twelve equivalent Pt atoms to form a mixture of distorted face and corner-sharing KPt12 cuboctahedra. There are six shorter (3.18 Å) and six longer (3.28 Å) K–Pt bond lengths. Pt is bonded in a 4-coordinate geometry to four equivalent K and six equivalent Pt atoms. There are two shorter (2.72 Å) and four longer (2.78 Å) Pt–Pt bond lengths.

KPt₃晶体属于六方晶系P6₃/mmc空间群。其晶体结构为三维结构。K原子与12个等价的Pt原子成键，形成兼具畸变面共享与角共享特征的KPt₁₂立方八面体配位多面体，其中包含6条键长为3.18 Å的较短K-Pt键与6条键长为3.28 Å的较长K-Pt键。Pt原子采取四配位几何构型，分别与4个等价的K原子以及6个等价的Pt原子成键，其中包含2条键长为2.72 Å的较短Pt-Pt键与4条键长为2.78 Å的较长Pt-Pt键。
