“…The cations reside on centers of inversion and display very regular octahedral geometry with maximum deviation from ideal 90° bond angles of just under 5°. This feature is very similar to what is found in other cobalt sulfonates Leonard et al, 1999).…”

Key indicators: single-crystal X-ray study; T = 140 K; mean (C-C) = 0.002 Å; Hatom completeness 89%; disorder in solvent or counterion; R factor = 0.035; wR factor = 0.098; data-to-parameter ratio = 23.4.The title compound, [Co(H 2 O) 6 ][H 3 NC 10 H 5 (SO 3 ) 2 ] 2 Á4H 2 O, is part of an isostructural family that includes the nickel(II) and zinc(II) analogues. The salts contain centrosymmetric hexaaquametal cations and protonated ammonionaphthalenedisulfonate anions arranged in alternating layers. The anions stack so that the charged groups face the cationic layers, maximizing electrostatic interactions. The non-coordinated water molecules are located in the cation layers. An extensive network of strong near-linear N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds involving the ammonio group, water molecules and sulfonate O atoms further anchors the packing. One of the uncoordinated water molecules is disordered over at least two sites (modelled over two positions with almost equal site occupancies).

“…The title compound is isostructural with its nickel(II) (Gunderman, Kabell et al, 1997) and zinc(II) (Genther et al, 2007) analogues.

“…Merging the data in the orthorhombic symmetry gives R int = 0.27. (I) is isomorphous with [Co(H 2 O) 6 ](OTs) 2 (Cabaleiro-Martõ Ânez et al, 2000) and pseudo-isomorphous with a number of [Ni(H 2 O) 6 ]X 2 salts, where X is PhSO 3 (Groh et al, 1990), p-ClC 6 H 4 SO 3 (Bernardinelli et al, 1991) and p-H 2 C CHÐ C 6 H 4 SO 3 (Leonard et al, 1999). The similarity of the latter structure with the rest is somewhat obscured by the fact that it has been reported in the P2 1 /c setting rather than in P2 1 /n, which corresponds to the reduced cell.…”

“…The unit cell and space group have been reported previously (Corbridge et al, 1966) but this is the ®rst complete structure determination. As is typical for aminesubstituted sulfonic acids (Gunderman & Squattrito, 1996;Leonard & Squattrito, 1997), the molecules exist in the zwitterionic ammoniosulfonate form, with the acidic H atom on the amine N atom (Fig. 1).…”

“…In our previous studies, there is precedence for both differences and a lack of difference in the sulfonate salts of these metals. The Mn, Co and Ni salts of 4-styrenesulfonate are isostructural, with no extra water beyond that coordinated to the metal cations (Leonard et al, 1999). For 4-aminonaphthalene-1-sulfonate, the Co and Ni salts are isostructural orthorhombic trihydrates, while the Mn salt is a monoclinic dihydrate (Morris et al, 2003).…”

5-Ammonionaphthalene-1-sulfonate monohydrate, C10H9NO3S x 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-H...O and O-H...O 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 x 3 H2O, (II), and hexaaquanickel(II) bis(5-aminonaphthalene-1-sulfonate) trihydrate, [Ni(H2O)6](C10H8NO3S)2 x 3 H2O, (III), in which layers of hexaaquametal(II) complexes alternate with layers of 5-aminonaphthalene-1-sulfonate anions. The cations reside on twofold rotation axes and display regular octahedral coordination. The additional water molecules are found in the inorganic layer between the complex cations, one on a twofold axis and one in a general position. The anions are packed in a herring-bone arrangement with the rings of neighboring rows of anions approximately 43 degrees out of parallel. The NH2 and SO3(-) groups line the surface of the layer, where they participate in numerous hydrogen bonds with the water molecules. Whereas the Mn and Ni salts are orthorhombic, the Co salt, hexaaquacobalt(II) bis(5-aminonaphthalene-1-sulfonate) dihydrate, [Co(H2O)6](C10H8NO3S)2 x 2 H2O, (IV), crystallizes in a triclinic cell of similar dimensions, with the cations situated on centers of inversion. The overall packing is very similar to that of the Mn and Ni salts, with the main differences being the absence of the solvent water molecule on the special position and subtle modifications in the positioning of the anions within their layers. This series of salts is compared with those of the same metals with the 5-aminonaphthalene-2-sulfonate and 4-aminonaphthalene-1-sulfonate isomers, allowing for similarities and differences in packing to be discussed on the basis of the differing substitution of the naphthalene ring and, in some cases, differing degrees of hydration.
