Abstract K2SnOF4 and K2WO3F2 were synthesized via a high-pressure/high-temperature route. Single-crystal analysis showed that both substances crystallize in the orthorhombic crystal system with space group Pnma and are isostructural to each other. The main motifs of the structures are octahedral [SnO2F4]4− and [WO4F2]4− entities for K2SnOF4 and K2WO3F2, respectively. Within the structures, these units are connected to quasi-isolated infinite chains. The substances were further characterized via powder X-ray diffraction, EDX and FT-IR spectroscopy. Doping of K2SnOF4 with Mn4+ yielded a red phosphor material which was analyzed by luminescence spectroscopy. The emission maximum is located at λ max = 631 nm.

K2SnOF4 和 K2WO3F2 – 不同但相似

摘要 K2SnOF4 和K2WO3F2 是通过高压/高温路线合成的。单晶分析表明,这两种物质都在具有空间群 Pnma 的正交晶系中结晶,并且彼此具有同构。结构的主要图案分别是 K2SnOF4 和 K2WO3F2 的八面体 [SnO2F4]4- 和 [WO4F2]4- 实体。在结构内,这些单元连接到准隔离的无限链。这些物质通过粉末 X 射线衍射、EDX 和 FT-IR 光谱进一步表征。用 Mn4+ 掺杂 K2SnOF4 产生红色磷光体材料,通过发光光谱对其进行分析。发射最大值位于 λ max = 631 nm。
