In the title complex, [Ni(C₁₁H₉ClN₃O₂)₂]·4H₂O, the Ni atom is coordinated by four N atoms and two O atoms derived from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The cis-N₄O₂ donor set defines a distorted octahedral geometry. In the crystal structure, the complex and water molecules are linked by O—H⋯O hydrogen bonds.

Comment top

Recently we reported the crystal structures of bis[6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]zinc(II) trihydrate (Yin et al., 2007) and bis[3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]cobalt(II) 2.5- hydrate (Zhao et al., 2007). As a continuation of these investigations, the crystal structure of the title complex, (I), is described.

In (I), Fig. 1, the Ni atom is six-coordinated by four N atoms and two O atoms derived from two uninegative tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The resultant cis-N₄O₂ donor set defines an approximate octahedral geometry with the range of the angles around Ni(II) center being 76.82 (9) to 178.42 (10)°. A complex network of O—H···O hydrogen bonds involving the ligand-O and water molecules of crystallization consolidate the crystal structure (Table 1).

Experimental top

6-(3,5-Dimethyl-1H-pyrazol-1-yl)picolinic acid (1 mmol, 250 mg) was dissolved in anhydrous alcohol (15 ml) and stirred until a clear solution resulted. A solution of NiCl₂.6H₂O (0.5 mmol, 113 mg) in anhydrous alcohol (10 ml) was then added. After keeping the resulting solution in air to evaporate about half of the volume, blue prisms of (I) formed. The crystals were isolated, washed with ethanol three times and dried in a vacuum desiccator using silica gel as the dessicant; yield 75%. Elemental analysis: Found: C 41.70, H 4.25, N 13.20, O 20.35%. C₂₂H₂₆NiN₆O₈ requires: C 41.80, H 4.15, N 13.30, O 20.25%.

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.
