Triaqua(2,2′-bipyridine-κ²N,N′)(5-nitroisophthalato-κO¹)zinc(II) monohydrate

In the title compound, [Zn(C₈H₃NO₆)(C₁₀H₈N₂)(H₂O)₃]·H₂O, the Zn^II cation is hexacoordinated by a chelating 2,2′-bipyridine ligand, one carboxylate O atom from a 5-nitroisophthalate dianion and three water molecules in a slightly distorted octahedral geometry. The structure contains isolated neutral complexes, in contrast to coordination polymers formed by Mn^II, Co^II and Cu^II with the same ligand set. An extensive network of hydrogen bonds is formed between the water molecules and the carboxylate groups.

Comment top

In recent years, carboxylic acids have been widely used in materials science as polydentate ligands which can coordinate to transition-metal or rare-earth cations to yield complexes with interesting or useful properties. For example, Kim et al. (2001) have focused on the syntheses of transition-metal complexes containing benzene carboxylate and rigid aromatic pyridine ligands in order to study their electronic conductivity and magnetic properties. The importance of transition-metal dicarboxylate complexes motivated us to pursue synthetic strategies for these compounds, using 5-nitroisophthalic acid as a polydentate ligand.

Experimental top

A mixture of zinc dichloride (0.5 mmol), 2,2'-bipyridine (0.5 mmol), and 5-nitroisophthalic acid (0.5 mmol) in H₂O (8 ml) and ethanol (8 ml) was sealed in a 25 ml Teflon-lined stainless steel autoclave and kept at 413 K for three days. Colourless crystals were obtained after cooling to room temperature with a yield of 27%. Elemental analysis calculated: C 42.97, H 3.78, N 9.55%; found: C 42.86, H 3.76, N 9.51%.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
