(Received 18 December 2008; accepted 7 January 2009; online 10 January 2009)

In the title complex, (C5H6ClN2)(C7H8NO)[CoCl4], the CoII ions are tetra­hedrally coordinated. The crystal structure is built from hydrogen-bonded centrosymmetric tetra­mers of tetra­chloridocobaltate(II) dianions and 3-amino-2-chloro­pyridinium cations, additionally strengthened by significant π–π stacking of pyridinium rings [interplanar distance 3.389 (3) Å]. The tetra­mers are linked by N—H⋯Cl hydrogen bonds into chains; the second kind of cations, viz. 2-acetyl­pyridinium, are connected by N—H⋯Cl hydrogen bonds to both sides of the chain. The Co—Cl bond lengths in the dianion correlate with the number of hydrogen bonds accepted by the Cl atom. An intramolecular C—H⋯Cl interaction is also present.

Comment top

Schiff bases are often employed as ligands in the metal ion - directed assembly of coordination architectures (Radecka-Paryzek et al., 2005). Such complexes are used as luminescent probes in the visible and near-IR spectral domains (Yam et al., 1999), as precursors for doped materials where metal centers must be implemented at a fixed distance and as catalysts for specific DNA (Mukherjee et al., 2005) and RNA (Häner & Hall, 1999) cleavage. In the course of our studies of Schiff base metal complexes with novel chemical properties we have accidentally synthesized the interesting example of three-component complex with CoCl4 dianion and two different cations: 3-amino-chloropyridinium (a) and 2-acetylpyridinium (b) (Scheme & Fig. 1).

Both cations are planar within the experimental error; the maximum deviation from the least-squares planes are as small as 0.006 (2)Å in (a) and 0.002 (2)Å in (b). In the latter case the plane of acetyl group makes a dihedral angle of 11.0 (2)° with the ring plane. In the crystal structure, two motifs involving the (a) cations, R44(12) and R44(18, act together to make the double chain of these cations and dianions along [110] direction. The R44(18) motif is additionally strengthened by the π-π stacking of pyridinium rings. The distance between the exactly parallel least-squares planes is 3.389 (3) Å, with relatively small offset of only 0.708 Å. The second kind of cations, (b) are joined - by means of the N—H···Cl hydrogen bonds - to the chain, on its both sides (Fig. 2). Additionally, relatively short and linear C—H···Cl hydrogen bond is accepted by the Cl4 atom, not involved in any N—H···Cl interactions.

The Co is tetrahedrally coordinated in the anions (Fig. 1); the distortion from the ideal geometry is small. The angles are close to the ideal values {106.68 (3) - 112.35 (3)°}. The differences in the Co—Cl bond lengths correlate with the number of hydrogen bonds accepted by the Cl atom: Co—Cl2 bond is the longest {2.2893 (7) Å; Cl2 accepts two h.b.'s}, Co—Cl1 and Co—Cl3 have similar, intermediate lengths of 2.2751 (7)Å and 2.2771 (7) Å, and Cl4, which accepts only C—H···Cl hydrogen bonds, makes the shortest Co—Cl bond of 2.2593 (7) Å.

Experimental top

To a mixture of cobalt chloride hexahydrate (18.2 mg; 0.08 mmol) and 2-acetylpyridine (9.4 mg; 0.08.m mol) in acetonitrile (20 cm3), 3-amino-2-chloropyridine (0.01 g; 0.08 mmol) in acetonitrile (10 cm3) was added dropwise with stirring. The reaction mixture was stirred for 24 h, at room temperature. The green crystals were obtained by slow diffusion of chloroform to the acetonitrile solution.

Refinement top

Hydrogen atoms from N—H groups were located in difference Fourier maps and isotropically refined; other H atoms were located geometrically and refined as the 'riding model' with Uiso's set at 1.2 (1.4 for methyl group) times Ueq's of appropriate oxygen atoms.

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.
