In the title compound, [Ni(C11H9ClN3O2)(C7H3NO4)]·2H2O, the NiII atom is coordinated by two N atoms and one O atom of 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate and by one N atom and two O atoms of pyridine-2,6-dicarboxylate in a distorted octahedral coordination. In the crystal structure, molecules are linked together by intermolecular O-H
O hydrogen bonds. One water molecule is disordered over two positions; the site occupancies are ca 0.53 and 0.47.
3-chloro-(6-(3,5-dimethyl-1H-pyrazol-1-yl))picolinic acid, pyridine-2,6-dicarboxylic acid and NiCl2.6H2O were available commercially and were used without further purification. Equimolar 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinic acid (0.5 mmol, 125 mg) and pyridine-2,6-dicarboxylic acid (0.5 mmol, 83 mg) were dissolved in anhydrous alcohol (15 ml). The mixture was stirred to give a clear solution, To this solution was added NiCl2.6H2O (0.5 mmol, 113 mg) in anhydrous alcohol (10 ml). After keeping the resulting solution in air to evaporate about half of the solvents, dark red prisms of the title compound were formed. The crystals were isolated, washed with alcohol three times and dried in a vacuum desiccator using silica gel (Yield 75%). Elemental analysis: found: C, 42.25; H, 3.26; N, 10.88; O, 25.17; calc. for C18H16ClNiN4O8: C, 42.35; H, 3.16; N, 10.98; O, 25.07.
All the H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with C—H distances of 0.93 Å and 0.96 Å for aromatic and methyl C atoms with Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.5Ueq(C), respectively. One of two water molecules is disorder on two positions with ratio 0.531 (7)/0.469. The H atoms of water molecules were located from the difference Fourier map and constrained to ride on their parent atoms with O—H distances of 0.85 Å with and Uiso(H) = 1.2Ueq(O).

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 > 2σ(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. |

In recent years, there has been an increasing interest in the coordination chemistry due to the increased recognition of it's role in catalysis enzymatic reactions, magnetism and molecular architectures (Costamagna et al., 1992; Bhatia et al., 1981). We report here the crystal structure of a new nickel(II) complex with the ligand 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl) picolinic acid (CDPA) and pyridine-2,6-dicarboxylate (PDBL). (I) (Fig. 1).
The title compound, (I), consists of a central asymmetric Triclinic nickel(II) complex cation,two uncoordinated water molecules. In the cation (Fig. 1), the Ni atom is six-coordinated by three atoms and three O atoms from CDPA and PDBL ligands. The Ni(II) atom is a slightly distorted octahedral environment. The Ni—O bond length is 2.0699 (19), 2.0702 (18) and 2.2263 (18) Å, The Ni—N distances range from 1.973 (2) to 2.103 (2) Å, i.e. normal values. The C1—C2 bond length is 1.526 (3) Å, being in the normal C—C ranges in nickel carboxylate complexes. The angles around Ni(II) atom are from 76.78 (8) to 177.69 (8)°.
In the title compound, the oxygen atoms contribute to the formation of intermolecular hydrogen bonds involving water O atom. (Table 1 and Fig. 2).
