The title compound, [Co(H2O)6][H3NC10H5(SO3)2]2·4H2O, 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—H...O and O—H...O 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).

Comment top

Metal sulfonate salts have been actively studied in recent years as part of the growing field of mixed inorganic-organic structures of interest in crystal engineering. Key results have been summarized in two recent reviews (Cote & Shimizu, 2003; Cai, 2004).

We have characterized a variety of naphthalenesulfonate salts of main group and transition metals (Gunderman & Squattrito, 1995; Gunderman, Kabell et al., 1997; Morris et al., 2003; Downer et al., 2006) with the goal of discerning structural trends as functions of metal cation and substitution of the sulfonate group. As part of our continuing interest in this chemistry, we have synthesized a series of salts of 3-aminonaphthalene-1,5-sulfonate with divalent transition metals.

The result is a family of isostructural salts of formula [M(H2O)6](H3NC10H5(SO3)2)2·4H2O where M = Co, Ni & Zn. The title cobalt compound consists of hexaaquacobalt(II) cations, 3-ammonionaphthalene-1,5-disulfonate anions, and water molecules of crystallization (Fig. 1). Owing to the protonation of the amine group, each anion carries a single negative charge and the salt has the same 1:2 stoichiometry as would be observed with a monosulfonate anion. 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 (Gunderman, Dubey & Squattrito, 1997; Leonard et al., 1999).

The crystal packing (Fig. 2) is typical for transition metal arene- and naphthalenesulfonates (Chen et al., 2002; Gunderman, Dubey & Squattrito, 1997), consisting of alternating layers of hexaaquametal cations and sulfonate anions parallel to the ac plane, with the anions positioned so that the charged groups (i.e., NH3+ and SO3_) line the surface of the layer. The anions are positioned so that all the rings are parallel with contacts between adjacent rings of ca 3.7 Å. Neighboring rows of anions running along the a axis have the ammonio groups inverted. The water molecules of crystallization are located in between the cations in close association with the charged groups and coordinated water molecules so as to participate in hydrogen bonding interactions. One of the two crystallographically independent water molecules is disordered over at least two positions.

The layers are held together by a series of strong O—H···O and N—H···O hydrogen bonds involving water and ammonio donors and sulfonate and water acceptors (Table 2).

Experimental top

The title compound was prepared by direct reaction of Co(NO3)2·6H2O and disodium 3-aminonaphthalene-1,5-disulfonate (1:2 stoichiometry) in aqueous solution. Following approximately one hour of heating, during which most of the reactants dissolved, the resulting solution was gravity filtered and set out in open air. Upon evaporation of the water, many small reddish, needles of (I) were recovered.

Refinement top

The O11 atom, corresponding to one water of crystallization, was found to be disordered and was refined on split positions ca 0.5 Å apart with occupancy factors constrained to sum to 1. Final occupancies were roughly 53% (O11A) and 47% (O11B). The B site has a significantly prolate displacement ellipsoid, but further splitting of the position could not be successfully modeled. The H atoms attached to the disordered water molecule could not be located. All other H atoms were located in difference maps and positionally refined either freely or with distance restraints of O—H = 0.82 (2) Å, and with Uiso(H) = 1.2Ueq(N,C) or Uiso(H) = 1.5Ueq(O).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
