In the structure of the title compound, 2[Ag(C₁₀H₈N₂)(H₂O)](C₇H₆NO₂)(NO₃)·H₂O, the Ag^I atom is three-coordinated in a T-shaped configuration by two N atoms from two symmetry-related 4,4′-bipyridine (bipy) ligands at short distances and by one water O atom at a longer distance. Each bipy ligand bridges two neighbouring Ag^I atoms, forming a chain structure extending parallel to [101]. The complete 4-aminobenzoate anion, the nitrate anion and the uncoordinated water molecule are located on mirror planes: together with the coordinated water molecule, they form N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, stabilizing the crystal structure.

Comment top

Silver coordination polymers have received intense interests because of their interesting structural features and potential applications (Zhang et al., 2008). We report here the synthesis and structure of the title compound, [Ag₂(C₁₀H₈N₂)₂(H₂O)₂].(C₇H₆NO₂).NO₃.H₂O, (I).

In the crystal structure of compound (I), the Ag^I atom is three-coordinated by two nitrogen atoms from two symmetry-related bipy (bipy = 4,4'-bipyridine) ligands and one water water molecule in a T-shaped coordination configuration (Fig. 1). Each bipy ligand bridges two neighboring Ag^I atoms to form a chain structure along [101]. Further, L anions (L = 4-aminobenzoate), the nitrate anion, and the uncoordinated water molecule form N—H···O and O—H···O hydrogen bonds, stabilizing the structure of (I).

Experimental top

A mixture of AgNO₃ (1 mmol), NaOH (0.040 g, 1 mmol) and 4-aminobenzoic acid (1 mmol) in water (15 ml) was stirred for 10 min at room temperature. Then 4,4'-bipyridine (1 mmol) was added to the solution with stirring for 30 min and a white precipitate was obtained. The precipitate was dissolved by dropwise addition of ammonia (5 M). Single crystals were obtained by slow evaporation of the solution at room temperature.

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 > 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.
