The compounds (NH4)(3)AsS4.5NH(3) (1) and (NH4)(3)SbS4.8 NH3 (2) were prepared by the reaction of Na3AsS4 and Na3SbS4 with a proton-charged ion exchange material in liquid ammonia and characterized by low temperature single crystal X-ray structure analysis. The ammonium-ammoniates show H3N-H...N-hydrogen bonds between the ammonium ion and ammonia molecules ranging from 1.86 to 2.55 Angstrom (DHA-angles: 145 -173degrees) and H3N-H...S-bonds to the thioanions between 2.36 and 2.97 Angstrom (DHA-angles: 130-176degrees). The former of the interactions are responsible for the formation of [(NH3)(2)H](+), [(NH3)(3)H](+) and [(NH3)(4)H](+)-complexes, the last two of which were characterized by X-ray analysis for the first time.
