Abstract: 5-Ammonionaphthalene-1-sulfonate monohydrate, C10H9NO3S·H2O, contains layers of zwitterionic molecules with the acidic sulfonic acid H atom transferred to the amine N atom. Within each layer, the charged groups (NH3+ and SO3-) are directed to the surface of the layer and are inverted on adjacent molecules. The naphthalene rings in a given layer are all parallel. The layers are held together by N-HO and O-HO hydrogen bonds involving the ammonium, sulfonate and water atoms. The Mn and Ni salts crystallize as fully aquated trihydrates, namely hexaaquamanagnese(II) bis(5-aminonaphthalene-1-sulfonate) trihydrate, [Mn(H2O)6](C10H8NO3S)2·3H2O, (II)
Formula: C10H9NO3S·H2O, [Mn(H2O)6](C10H8NO3S)2·3H2O, [Ni(H2O)6](C10H8NO3S)2·3H2O and [Co(H2O)6](C10H8NO3S)2·2H2O
