Bis(6,6′-dimethyl-2,2′-dipyridyl-κ²N,N′)silver(I) tetrafluoridoborate

K. K. Klausmeyer, F. Hung-Low and A. Renz

In the title compound, [Ag(C₁₂H₁₂N₂)₂]BF₄, the Ag^I atom is four-coordinated by two chelating bipyridine groups; thus the crystal structure presents a 2:1 ligand-to-metal ratio. The angles around the metal center describe a distorted tetrahedral geometry, with the Ag—N distances falling in the range of reported values. The pyridyl rings of the bipyridine ligands are essentially coplanar with small twisting angles between the corresponding mean planes.

Comment top

Early reports of 2,2^'-dipyridyl complexes with a variety of metals, such as Pd, Cu, Co, and Zn (Newkome et al., 1981), have been accompanied by a considerable amount of work on the study the coordination chemistry of these and the related methyl-substituted dipyridyls (Kaes et al., 2000). More recently, the study of these bipyridine ligands with silver salts has shown a predominant coordination form of the type [AgL₂]⁺X^-, which form a five-membered ring that can stabilize different oxidation states of the silver center (I or II) (Effendy et al., 2007; Di Nicola et al., 2007). This is a common mode of binding for these bipyridine fragments, since they are almost universally chelating bidentate ligands by virtue of the close proximity of the aromatic rings. Additionally, it has been seen that the silver coordination environment parameters vary widely with respect to steric changes within the ligand, and external forces associated with the counterion, can affect the formation of close metal—metal interactions. Herein, we continue to enhance the library of silver coordination structures containing substituted bipyridine ligands, by reporting the formation of the title compound, formed by the reaction between the 6,6^'-dimethyl-2,2^'dipyridyl ligand and the silver tetrafluoroborate salt, which presents a 2:1 ligand to metal ratio.

The title compound consists of two 6,6^'-dimethyl-2,2^'-dipyridyl ligands bound to the silver center in a chelating fashion, and the tetrafluoroborate is a non coordinating counteranion. According to the angles around the metal atom, a highly distorted tetrahedral geometry is described with values ranging between 72.30 (6) and 137.80 (6)°. The two pyridyl rings corresponding to the N1 and N2 atoms are nearly coplanar with a twist angle of 6.59 (12)° between the two mean planes. In contrast, the pyridyl rings of the second bipyridine ligand corresponding to N3 and N4, describe a larger angle with a value of 12.19 (10)°.

Experimental top

The title compound was obtained by mixing AgBF₄ (0.057 g, 0.3 mmol) and 6,6^'-dimethyl-2,2^'-dipyridyl (0.110 g, 0.6 mmol) in 10 ml of acetonitrile. The mixture was stirred for 10 min and the solvent removed in vaccuo. Diffraction-quality crystals were obtained by slow diffusion of hexanes into a concentrated THF solution of the title compound in the presence of air.

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.
