Crystals of diammine gold(I) chloride ammonia (1/4), [Au(NH3)(2)]Cl center dot 4NH(3), have been grown from solutions of Au Cl in liquid ammonia. The X-ray diffraction analysis (at 123 K) has shown that the crystals feature an extensive network of hydrogen bonds between the [H3N-Au-NH3](+) cations (with C-i symmetry) and the Cl- anions, including also the ammonia molecules. There is no evidence for an emerging increase of the coordination number of the gold atom by adopting another ammonia molecule or by approaching a chloride anion. Moreover, the geometry of two distant and angular N-H center dot center dot center dot Au contacts is not a strong support of hydrogen bonds recently amply discussed in the literature.
