Materials Data on Pr2Mg by Materials Project

MgPr2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two MgPr2 sheets oriented in the (1, 0, 0) direction. Mg is bonded in a body-centered cubic geometry to eight Pr atoms. There are a spread of Mg–Pr bond distances ranging from 3.40–3.43 Å. There are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 4-coordinate geometry to four equivalent Mg atoms. In the second Pr site, Pr is bonded in a 12-coordinate geometry to four equivalent Mg atoms.

MgPr₂以单斜晶系（monoclinic）C2/m空间群（space group）结晶。该结构为二维结构，包含两片沿(1,0,0)晶向取向的MgPr₂片层。Mg原子采取体心立方配位几何，与8个Pr原子成键；Mg-Pr键的键长范围为3.40~3.43 埃（Å）。该体系存在两个不等价的Pr原子位点：在第一个Pr位点中，Pr原子采取四配位几何，与4个等价的Mg原子成键；在第二个Pr位点中，Pr原子采取十二配位几何，与4个等价的Mg原子成键。
