Abstract top

In the title compound, [Co(C8H4O7S)(C12H8N2)(H2O)3]·H2O, the CoII cation is coordinated by one sulfoisophthalate dianion, one bidentate phenathroline (phen) molecule and three water molecules in a distorted cis-CoN2O4 octahedral geometry. In the crystal structure, aromatic [pi]-[pi] stacking occurs [centroid-centroid distances 3.7630 (14) and 3.7269 (15) Å], as well as an extensive O-H...O and C-H...O hydrogen-bonding network

Comment top

As part of our ongoing studies of aromatic π–π stacking in coordination complexes (Li et al., 2005; Liu et al., 2006), the title CoII compound, (I), incorporating the sulfoisophthalate ligand has been prepared and its crystal structure is reported here (Fig. 1).

The CoII cation in (I) is coordinated by one sulfoisophthalate dianion, one bidentate phenathroline (phen) molecule and three water molecules in a distorted CoN2O4 octahedral geometry (Table 1). Among the two carboxyl groups of the sulfoisophthalate, the C13-carboxyl group is deprotonated and the difference between C13—O1 and C13—O2 bond distances is small whereas the C20-carboxyl group is not deprotonated and the difference between the C20—O3 and C20—O4 bond distances is larger (Table 1).

This is in agreement with those found in related structures, e.g. catena-((µ3-5-carboxy-3-sulfonatobenzoato)aqua(phenanthroline)lead(II) monohydrate (Li et al., 2005) and bis(µ2-aqua)hexaaquabis(5-sulfoisophthalato)dicadmium(II) (Liu et al., 2006). The C13-carboxyl group is hydrogen bonded (as an acceptor) to the coordinated water molecule while the C20-carboxylo group is hydrogen bonded (as a donor) to the uncoordinated water molecule (Fig. 1). An extensive O—H···O and C—H···O hydrogen bonding network helps to consolidate the packing (Table 2).

A partially overlapped arrangement is observed between nearly parallel phen ring system and the benzene ring of the sulfoisophthalate dianion from an adjacent complex (Fig. 2). The centroid-to-centroid distances of 3.7630 (14) Å between the N1-pyridine and C16i-benzene rings and 3.7269 (15) Å between the C6-benzene and C16i-benzene rings [symmetry code: (i) 1 - x, -y, 1 - z] indicate the existence of π–π stacking between phen and sulfoisophthalate of the adjacent molecule.

Experimental top

A water–ethanol solution (15 ml, 2:1 v/v) containing monosodium 5-sulfoisophthalate (0.27 g, 1 mmol), sodium carbonate (0.053 g, 0.5 mmol), 1,10-phenanthroline (0.10 g, 0.5 mmol) and cobalt nitrate hexahydrate (0.29 g, 1 mmol) was refluxed for 3 h. After cooling to room temperature the solution was filtered. Red prisms of (I) were obtained from the filtrate after one week.

Refinement top

The carboxyl H and water H atoms were located in a difference Fourier map and refined as riding in as-found relative positions with Uiso(H) = 1.5Ueq(O). Aromatic H atoms were placed in calculated positions with C—H = 0.93 Å and refined in riding mode with Uiso(H) = 1.2Ueq(C).

Special details top

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.
