In the title compound, [Ag(BF₄)(C₁₄H₁₂N₂O₄)]_n, the coordination of the Ag⁺ ion is trigonal–bipyramidal with the N atoms of two ethane-1,2-diyl bis(pyridine-3-carboxylate) ligands in the apical positions and three F atoms belonging to different tetrafluoridoborate anions in the equatorial plane. The material consists of infinite chains of [Ag(C₁₄H₁₂N₂O₄)] units running along [001], held together by BF₄⁻ bridging anions.

Comment top

The design of polymeric organic-inorganic materials with novel topologies and structural motifs is of current interest in the field of coordination chemistry (Blake et al., 1999). This paper forms part of our continuing study of the synthesis, structural characterization and physical properties of coordination polymers (Brito et al., 2011). We report here the crystal structure of the title compound (Fig.1). It crystallizes as colorless needles, which were found to be stable to air and light. In the title compound, the coordination of the Ag^I atom is a trigonal bipyramid with the N atoms of two 1,2-diyl-bis(pyridine-3-carboxylate)ethane ligands in the apical positions and three F atoms belonging to different tetrafluoroborate anions in the equatorial plane. The Ag–N distances are 2.145 (6) and 2.155 (6) Å and the Ag–F distances are 2.832 (8) Å, 2.972 (7) Å and 3.168 (9) Å. The N–Ag–N angle [168.8 (3)°] is not far from being linear and the Ag—N vectors are almost perpendicular to the Ag—F vectors [76.7 (3)° to 103.1 (3)°]. The F–Ag–F angles are 106.4 (2)°, 120.7 (2)° and 127.4 (2)°. The molecular dimensions of the 1,2-bis(3-pyridyl)ethane ligand are within normal ranges and the ethylene moiety retains the gauche conformation (Brito et al., 2010). The material consists of infinite chains of [Ag(C₁₄H₁₂N₂O₄)] moieties running along [001] held together by BF₄^- bridging anions (Fig. 2).

Experimental top

A solution of AgBF₄ (19.4 mg, 0.1 mmol) in water was slowly added to a solution of the ligand (27.2 mg, 0.1 mmol) in THF (4 ml). Colorless single crystals suitable for X-ray were obtained after a few days (82%).The FT—IR (KBr, cm^-1): 1724 s, 1609, 1434 m, 1280 s, 742 m.

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.
