摘要：
The title compound, ammonium chromium(III) bis(sulfate) dodecahydrate, is composed of discrete NH4+ cations, [Cr(H2O)(6)](3+) cations, SO42- anions and water molecules. The Cr and N atoms are located on special positions of site symmetry (3) over bar; the S atom and one of the O atoms bonded to it are located on a threefold rotation axis. The crystal packing is stabilized by several hydrogen bonds.
