SODIUM 1,12-DODECYLENE DISULFATE HYDRATE

There are two independent dodecylene disulfate molecules in the crysta l of 2Na(+).Cl(1)2H(24)O(8)S(2)(2-).2/3H(2)O, one with a centrosymmetr ic conformation, its center lying on a crystallographic center of symm etry, the second with an asymmetric conformation, which is partially d isordered. The molecules form a layer structure parallel to the ab pla ne, the polar parts of neighbouring molecular layers connecting via co ordination to the Na+ ion. Additionally, there are hydrogen bonds betw een the water molecule and two sulfate groups.
