Silver acetate AgOAc reacts with dry liquid ammonia under the formation of colorless needle‐shaped crystals of diammine silver(I) acetate [Ag(NH 3 ) 2 ]OAc ( 1 ). The compound crystallizes in the monoclinic space group P 2 1 / c with a = 8.0205(2), b = 12.4161(3), c = 6.0938(2) Å, β = 107.741(4)°, and V = 577.98(3) Å 3 at 123 K with Z = 4. The crystal structure shows the presence of almost linear [Ag(NH 3 ) 2 ] + cations, which are arranged in a corrugated chain of equidistant silver atoms. The Ag–Ag distance is 3.1089(11) Å, which falls in the range of “argentophilic” interactions. After warming to room temperature and removal of the solvent, compound 1 was found unchanged as evidenced by powder X‐ray diffraction, thermogravimetric and mass‐spectrometric analysis, as well as IR and Raman spectroscopy.
