Undoped and Mg‐doped Pr₂MoO₆ oxymolybdate polycrystals and single crystals have been prepared by solid‐state reactions and flux growth. The compounds have been characterized by powder X‐ray diffraction, energy‐dispersive spectroscopy, inductively coupled plasma mass spectrometry, scanning transmission electron microscopy, single crystal X‐ray structure analysis, differential scanning calorimetry and thermogravimetry. The (MgO)_x(Pr₂O₃)_y(MoO₃)_z (x + y + z = 1) solid solution series has been shown to extend to x = 0.03. The structure of the Mg‐doped Pr₂MoO₆ single crystals can be represented as superimposed lattices of the main matrix (Pr₂MoO₆) and lattices in which Mo atoms are partially replaced by Mg. The incorporation of Mg atoms into the structure of Pr₂MoO₆ results in the disordering of the praseodymium and oxygen lattices. Both the polycrystalline and single‐crystal Mg‐doped samples are hygroscopic.

Mg掺杂的Pr2MoO6层状钼酸钼的合成，结构和性能。

通过固相反应和助熔剂生长制备了未掺杂和Mg掺杂的Pr ₂ MoO ₆氧钼酸多晶和单晶。这些化合物的特征在于粉末X射线衍射，能量色散光谱，电感耦合等离子体质谱，扫描透射电子显微镜，单晶X射线结构分析，差示扫描量热法和热重分析。已证明（MgO）_x（Pr ₂ O ₃）_y（MoO ₃）_z（x + y + z = 1）固溶体系列扩展到x= 0.03。Mg掺杂的Pr ₂ MoO ₆单晶的结构可以表示为主基质（Pr ₂ MoO ₆）的叠置晶格和其中Mo原子部分被Mg取代的晶格。将Mg原子掺入Pr ₂ MoO ₆的结构中导致the和氧晶格的无序化。多晶和单晶掺镁样品均具有吸湿性。
