The title compound, diammonium tricadmium tetrakis(sulfate) pentahydrate, (NH4)2Cd3(SO4)4·5H2O, was formed during an attempted synthesis of the langbeinite, (NH4)2Cd2(SO4)3. The structure has two layers, one containing Cd octahedra bridged by sulfate groups and the other containing edge-shared Cd octahedra, with NH4 units occupying interstitial positions. The layers are connected by way of Cd—O—S links.
