The perfluorohexane‐soluble and donor‐free silver compound Ag(A) (A=Al(ORF)4; RF=C(CF3)3) prepared using a facile novel route has unprecedented capabilities to form unusual and weakly bound complexes. Here, we report on the three dihalogen–silver complexes Ag(Cl2)A, Ag(Br2)A, and Ag(I2)A derived from the soluble silver compound Ag(A) (characterized by single‐crystal/powder XRD, Raman spectra, and quantum‐mechanical calculations). Catch a dihalogen: The donor‐free and coordinatively unsaturated silver compound Ag[Al(ORF)4] (RF=C(CF3)3) is slightly soluble in perfluorohexane. The compound takes up the simple and weakly basic dihalogen molecules Cl2, Br2, and I2 as ligands.
