The reaction of Co(NO3)2·3H2O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C7H3NO4)(C5H8N2)3]·H2O. The CoII atom is coordinated by one pyridine-2,6-dicarboxylate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octahedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure

An ethanol solution (6 ml) containing 3,5-Dimethyl-1-H-pyrazole(0.1153 g, 1.2 mmol) and Co(NO3)2.3H2O(0.0870 g, 0.3 mmol) was mixed with an aqueous solution (6 ml) of pyridine-2,6-dicarboxylic acid(0.0501 g, 0.3 mmol) and NaOH (0.0240 g, 0.6 mmol). The mixture was refluxed for 6 h. The solution was filtered after cooling to room temperature. Pink single crystals suitable for X-ray diffraction were obtained from the filtrate after 11 d.
The H atoms of water molecule were located in a difference Fourier map and refined freely. Methyl H atoms were placed in caculated positions with C—H distances = 0.96 Å and Uiso(H) = 1.5Ueq(C). Other H atoms were placed in caculated positions with C—H distances = 0.93 Å and N—H distances = 0.86 Å, and Uiso(H) = 1.5Ueq(C,N).

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. |

Complexes with pyrazole-based ligands are a frequent subject of chemical investigations giving an opportunity for a better understanding of the relationship between the structure and the activity of the active site of metalloproteins (Haanstra et al., 1990). Nowadays, attention is paid to the design of various pyrazole ligands, and some coordination modes of pyrazole complexes were reported (Grotjahn et al., 2003). In our systematic studies on transition metal comlexes with the pyrazole derivatives, the title compound was prepared and its X-ray structure is presented here.
The molecular structure of the title compound is shown in Fig. 1. The compound assumes a distorted octahedron geometry, formed by three 3,5-Dimethyl-1-H-pyrazole molecules and a pyridine-2,6-dicarboxylate. Tridentate ligand pyridine-2,6-dicarboxylate dianion chelates to the Co atom by a N atom of pyridine ring and two O atoms of carboxyl groups with a meridional configuration. Monodentate ligand 3,5-Dimethyl-1-H-pyrazole coordinated to the Co atom by N atoms of pyrazole rings. The bond distances of Co1—N1 and Co1—N4 are 2.0407 (16)Å and 2.0798 (16)Å (Table 1), which are shorter than the the bond distances of Co1—N2 and Co1—N6 with 2.2336 (17)Å and 2.2477 (17)Å.
