Abstract top

The asymmetric unit of the title compound, {[Ni(C7H3NO4)(C10H8N2)(H2O)]·H2O}n, contains one nickel cation chelated by a 2,2'-bipyridine ligand and further coordinated by two monodentate carboxylate groups belonging to two independent pyridine-3,4-dicarboxylate ligands and one water molecule. The NiII atom is six-coordinate, exhibiting octahedral geometry with three N and three O atoms. Each pair of neighbouring NiII cations is bridged by two independent pyridine-3,4-dicarboxylate ligands, which are coordinated to two further NiII cations through pyridine N atoms to give corrugated layers parallel to the (110) plane. The coordinated and uncoordinated water molecules act as donors in O-H...O hydrogen bonds.

Comment top

Complexes containing carboxylic acids have been the interest of chemists due to their potential applications, such as in catalysis, optics, information storage, medicine, molecular electrochemistry, biochemistry and biological pharmaceutics (Li et al., 1993; Go et al., 2004). Thus far, N-containing aromatic carboxylic acids have been widely used in dye intermediates, organic synthesis, sensitization materials, functional pigments, adipiodone and acetrizoic acid (An et al., 2000). Pyridinecarboxylic acids are also good ligands in coordination chemistry due to their strong coordination ability and versatile coordination modes, so much attention has been paid to them in recent decades (Baroni et al., 1996; Hundal et al., 2002). Here we report the new title nickel complex.

The asymmetric unit of the title compound contains one nickel cation chelated by a 2,2'-bipyridine ligand and further coordinated by two monodentate carboxylate groups belonging to two independent pyridine-3,4-dicarboxylate ligands and one water molecule (Fig. 1). NiII is six-coordinate, exhibiting octahedral geometry with three N and three O atoms. Each pair of neighboring NiII cations is bridged by two independent pyridine-3,4-dicarboxylate ligands, which are coordinated to two further NiII cations through pyridine N atoms to give corrugated layers parallel to the (110) plane (Fig. 2). The coordinated and uncoordinated water molecules act as donors in O—H···O hydrogen bonds.

Experimental top

A mixture of nickel(II) chloride (1 mmol), pyridine-3,4-dicarboxylic acid (1 mmol), and 2,2-bipyridine (2 mmol) in a mixed 1:1 solvent of H2O and ehanol in a 25 ml Teflon-lined stainless steel autoclave was kept at 473 K for ten days. Green crystals were obtained after cooling to room temperature, with a yield of 22%. Anal. Calc. for C17H15NiN3O6: C 49.04, H 3.61, N 10.12%; Found: C 48.89, H 3.41, N 10.06%.

Refinement top

The H atoms of the water molecules were located in a difference density map and were refined with distance restraints H···H = 1.38 (2) Å and O—H = 0.88 (2) Å, and with a fixed Uiso(H) of 0.80 Å2. All other H atoms were placed in calculated positions with a C—H bond distance of 0.93%A and Uiso(H) = 1.2Ueq(C).

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.
