Abstract

Single crystals of five compounds of a new structure type, the K₃Nd₅₂Ge₁₂O₁₀₀F₇ type, were grown from lanthanide rich reactions using a KF/KCl flux: K₃Ln₅₂Ge₁₂O₁₀₀F₇ (Ln = Nd, Eu), K₃Ln₅₂Ge₁₂O_100+δF_7-δ (Ln = Pr, Tb), and K₃Ca_0.872Nd_51.128Ge₁₂O_99.128F_7.872. The five compounds crystallize in the cubic space group I-43d with lattice parameter 22.0350(2) Å for K₃Nd₅₂Ge₁₂O₁₀₀F_7. The structure consists of a 3D checkerboard of LnX₈, LnX₇, LnX₆, and GeO₄ polyhedra, where X = O/F, and can be conceptually derived from the fluorite structure. K₃Eu₅₂Ge₁₂O₁₀₀F₇ exhibits the fluorescence typical of Eu³⁺.

从富镧通量生长反应中生长出五、六系碱系锗酸盐

利用KF/KCl助熔剂在富镧系反应中生长出了K3Ln52Ge12O100F7型新结构化合物：K3Ln52Ge12O100F7 （Ln = Nd, Eu）、K3Ln52Ge12O100+δF7-δ (Ln = Pr, Tb)和K3Ca0.872Nd51.128Ge12O99.128F7.872。K3Nd52Ge12O100F7在立方空间I-43d群中结晶，晶格参数为22.0350(2)Å。该结构由LnX8、LnX7、LnX6和GeO4多面体组成的三维棋盘组成，其中X = O/F，可以从萤石结构中概念推导出来。K3Eu52Ge12O100F7表现出典型的Eu3+荧光。
