Abstract top

In the title complex, [Cu(C7H4NO4)(C11H10N3O2)]·2H2O, the CuII atom is in a distorted octahedral geometry. The equatorial plane is formed by two N atoms and one O atom from 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate and by one N atom from pyridine-2,6-dicarboxylate (pdc). Two pdc O atoms occupy the axial positions. Water molecules are hydrogen bonded to the complex molecules, forming a two-dimensional sheet structure.

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) hemipentahydrate [Zhao et al., 2007]. As a continuation of these investigations, we report here the crystal structure of a new copper(II) complex with the ligand 3-chloro-6-(3,5-dimethyl-1 H-pyrazol-1-yl) picolinic acid (CDPA) and pyridine-2,6-dicarboxylate (PDBL). (Fig.1).

The title compound, (I), consists of a central asymmetric copper(II) complex cation and two uncoordinated water molecules. The compound is isostructural with its Ni derivative [Feng et al., 2008]. In the cation (Fig.1), the Cu atom is six-coordinated by three N atoms and three O atoms from CDPA and PDBL ligands. The three diagonal angles for the Cu(II) octahedron range from 150.7 (4)° to 173.7 (2)°, the dihedral angle between the planes of the two ligands is 80.5 (6)°, which indicates a slightly distorted octahedral geometry around the CuIIatom.

Analysis of the crystal packing of the title compound reveals the existence of multiple intermolecular O—H···O hydrogen bonds between the mononuclear subunits and the lattice water molecules (Figure 2), forming a two-dimensional hydrogen-bonded sheet perpendicular to the c-axis of the structure (Figure 3). In this sheet the two interstitial water molecules are connecting three complex molecules with each other: The protonated carboxyl oxygen atom O4 acts as a hydrogen donor towards O7 of one of the water molecules. One of the H atoms of O7 in turn binds with the second water molecule, and each one H atom of both water molecules acts as a hydrogen bonding donor towards the two carboxyl O atoms O5 and O6 of a neighboring complex. The last remaining water H atom (H8b) makes the connection to the third complex connected by the two water molecules (Figure 2). The carboxylate group that acts as an H bond acceptor towards both water molecules via both of its O atoms O5 and O6 exhibits a delocalized π system with nearly identical C—O distances.

Experimental top

3-Chloro-(6-(3,5-dimethyl-1H-pyrazol-1-yl))picolinic acid, pyridine-2,6-dicarboxylic acid and CuCl2.6H2O were available commercially and were used without further purification. Equimolar amounts of 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 CuCl2.6H2O (0.5 mmol, 113 mg) in anhydrous alcohol (10 ml). After keeping the resulting solution in air to evaporate about half of the solvents, blue 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, 44.85; H, 3.78; N, 11.65%. calc. for C18H18CuN4O8: C, 44.86; H, 3.76; N, 11.63%.

Refinement top

H atoms on C atoms were positioned geometrically and refined using a riding model with C–H = 0.93–0.96 Å and Uiso(H) = 1.2–1.5Ueq(C). The water H atoms were located in difference density Fourier maps and refined using a riding model with O–H = 0.82 Å and Uiso(H) = 1.5Ueq(O).

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.
