Abstract The double salt [(CH2)6N4CH3](NH4)SO4·H2O crystallizes in space groupP21/a, witha=12.994(2),b=6.319(1),c=15.082(2) Å, β=93.78(2)o, andZ=4. The structure was solved by the heavy-atom method and refined toR F 2=0.051 for 2478 MoKα data. The ammonium and sulfate ions are cross-linked by hydrogen bonds to form puckered layers disposed about the (001) family of planes. Each water molecule bridges a [(CH2)6N4CH3]+ ion and a sulfate group, so that the organic cations lying on both sides of a puckered layer have their methyl groups pointing inward and fitting into depressions.
