The title compound, (C3H7N6)2[Co(H2O)6][Co(C7H3NO4)2]2·4H2O, or (tataH)2[Co(H2O)6][Co(pydc)2]2·4H2O (where tata is 2,4,6-triamino-1,3,5-triazine and pydc is pyridine-2,6-dicarboxylic acid), was obtained by reaction of Co(NO3)2·6H2O with the proton-transfer compound (tataH)2(pydc) in aqueous solution. The [Co(pydc)2]2− anion is a six-coordinate CoII complex with a distorted octahedral coordination geometry. The structure also contains hexaaquacobalt(II) cations (site symmetry ), (tataH)+ cations and uncoordinated water molecules. The two(pydc)2− ligands in each [Co(pydc)2]2− anion are almost perpendicular to each other [dihedral angle between their mean planes = 82.3 (1)°]. There is extensive O—H⋯O, N—H⋯N, O—H⋯N and C—H⋯O hydrogen bonding in the structure, as well as π–π stacking between (pydc)2− ligands with an interplanar distance of 3.484 (15) Å.

The proton-transfer compound, (tataH)2(pydc), was prepared by the reaction of pyridine-2,6-dicarboxylic acid (pydcH2) with 2,4,6-triamino-1,3,5-triazine (tata). The reaction between Co(NO3)2.6H2O (115 mg, 0.5 mmol) in water (20 ml) and (tataH)2(pydc) (420 mg, 1.0 mmol) in water (20 ml), in a 1:2 molar ratio gave a violet crystalline compound after slow evaporation of the solvent at room temperature.
The N-bound and O-bound H atoms were located in difference Fourier maps and their positions were freely refined. Other H atoms were placed in calculated positions (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).
Recently, we have reported the reactions between Co(NO3)2.6H2O and two proton-transfer compounds: (GH)2(pydc) (where G is guanidine) and (pipzH2)(pydc) (where pipz is piperazine) in a 1:2 molar ratio. These reactions lead to the formation of the complexes (GH)2[Co(H2O)6][Co(pydc)2]2 (Sheshmani et al., 2006) and (pipzH2)[Co(H2O)6][Co(pydc)2]2.8H2O (Aghabozorg, Attar Gharamaleki et al., 2007), respectively.
Here, we report the synthesis and X-ray 1), and (tataH)+ cations. In the [Co(pydc)2]2- anions, the CoII atom is hexacoordinated by two N atoms (N1 and N2) and four O atoms (O1, O3, O5 and O7) from the carboxylate groups of two (pydc)2- groups that act as tridentate ligands. The coordination geometry is distorted octahedral, with atoms N1 and N2 occupying axial positions and the O atoms forming the equatorial plane. The N1—Co2—N2 angle deviates ca 7.7° from linearity. The mean Co—N and Co—O bond lengths for Co1 are 2.0214 (11) and 2.1658 (10) Å, respectively, consistent with similar complexes in the literature. The dihedral angle between the mean planes of the two (pydc)2- groups is 82.3 (1)°.

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. |

Recently, we have reported the reactions between Co(NO3)2.6H2O and two proton-transfer compounds: (GH)2(pydc) (where G is guanidine) and (pipzH2)(pydc) (where pipz is piperazine) in a 1:2 molar ratio. These reactions lead to the formation of the complexes (GH)2[Co(H2O)6][Co(pydc)2]2 (Sheshmani et al., 2006) and (pipzH2)[Co(H2O)6][Co(pydc)2]2.8H2O (Aghabozorg, Attar Gharamaleki et al., 2007), respectively.
Here, we report the synthesis and X-ray crystal structure of the title compound (Fig. 1). The compound contains [Co(pydc)2]2- anions, [Co(H2O)6]2+ cations (site symmetry 1), and (tataH)+ cations. In the [Co(pydc)2]2- anions, the CoII atom is hexacoordinated by two N atoms (N1 and N2) and four O atoms (O1, O3, O5 and O7) from the carboxylate groups of two (pydc)2- groups that act as tridentate ligands. The coordination geometry is distorted octahedral, with atoms N1 and N2 occupying axial positions and the O atoms forming the equatorial plane. The N1—Co2—N2 angle deviates ca 7.7° from linearity. The mean Co—N and Co—O bond lengths for Co1 are 2.0214 (11) and 2.1658 (10) Å, respectively, consistent with similar complexes in the literature. The dihedral angle between the mean planes of the two (pydc)2- groups is 82.3 (1)°.
There is extensive O—H···O, N—H···O, N—H···N and C—H···O hydrogen bonding in the structure, as well as π–π stacking between (pydc)2- ligands with an interplanar distance of 3.484 (15) Å (symmetry operator: -x, -y + 1, -z + 1). Atom O8 of the C14?O8 carboxyl group lies above the N2/C9–C13 ring with an O···centroid distance of 3.240 (1) Å (symmetry operator: x, -y + 1, -z).
