(Received 23 August 2012; accepted 7 September 2012; online 15 September 2012)

The structure of the title compound, [Co₂(C₁₉H₁₁F₂O₂)₄(C₅H₅N)₂(H₂O)₂]·2C₄H₁₀O, comprises two Co^II atoms in a distorted square pyramidal coordination environment, straddling a crystallographic inversion center with a Co⋯Co separation of 3.1923 (15) Å. Each Co²⁺ cation is coordinated by three O atoms of three 4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxylate ligands, one water O atom and one pyridine N atom, forming a CoO₄N polyhedron. Strong intramolecular O—H⋯O hydrogen bonds are observed between terminal metal-bound carboxylate groups and water O atoms.

Comment top

In metalloenzyme active sites, bimetal systems, ligated by four carboxylates and two histidines derived from the side chains of amino acids, are often found (Lippard et al. 1994; Holm et al. 1996). Here, we report the structure of the water-containing di-nuclear Co(II) complex which crystallizes in the triclinic space group P1 with one half molecule in the asymmetric unit. Bond distances to the metal are given in Table 1 with the structure of the molecule shown in Fig 1. and its strong intramolecular O—H···O interactions detailed in Table 2.

Experimental top

The sodium 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxylate (0.200 g, 0.602 mmol) was added into cobalt(II) trifluoromethansulfonate (0.529 g, 1.21 mmol) in 10 ml of tetrahydrofuran at room temperature. After stirring for 30 min, triethylamine (0.122 g, 1.21 mmol) and pyridine (0.134 g, 1.69 mmol) were added. Immediately, the color of solution was changed from light violet to dark purple. After 30 min, water (0.0218 g, 1.21 mmol) was further added. The volatile fractions were removed under the reduced pressure. Resulting purple powder was dissolved in dicloromethane and insoluble fractions were filtered off. Purple block-shaped crystals were collected upon vapor diffusion of diethyl ether. Yield = 2.26% (0.0230 g)

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.
