Hybrid organic‐inorganic cluster compounds A 2 [W 6 I 14 ] with A = Ph 4 P, PPN were prepared by cation exchange reactions from Cs 2 [W 6 I 14 ] with a corresponding organic halide; and a purification method for A 2 [W 6 I 14 ] compounds by column chromatography is introduced. Crystal structures of compounds were solved and refined based on single‐crystal X‐ray diffraction data. Photoluminescence properties of the new A 2 [W 6 I 14 ] compounds reveal orange to deep‐red emission on excitation between 300 and 500 nm. (PPN) 2 [W 6 I 14 ] is an exception among compounds with the [W 6 I 14 ] 2– ion, showing a solid‐state phosphorescence with a quantum yield (ϕ P ) in the order of 40 %.
