Comment top

Very strong cationic Lewis acids are only available in the presence of weakly coordinating counter-ions such as [B(C6F5)4]. These anions also play an important role in electrochemistry. The salt [nBu4N]+·[B(C6F5)4] possesses a low reactivity towards reducing and oxidizing agents. Moreover, conductance measurements show that the dissociation constant of [nBu4N]+·[B(C6F5)4] solutions in solvents with low polarity are greater than those of smaller traditional anions (LeSuer et al., 2004). Therefore, we are convinced that tetra-n-butylammonium tetrakis(pentafluorophenyl)borate, (I), is an ideal supporting electrolyte. According to a literature procedure (LeSuer et al., 2004), we have synthesized (I) and we report here the crystal structure.

Perspective views of the cation and anion of (I) are shown in Figs. 1 and 2, respectively. Bond lengths and angles can be regarded as normal (Cambridge Crystallographic Database; Version 1.6 plus three updates; Mogul Version 1.0; Allen, 2002). Compound (I) consists of discrete tetrakis(pentafluorophenyl)borate anions and tetra-nbutylammonium cations. The four n-butyl chains adopt an all-trans conformation.

Experimental top

Compound (I) was synthesized according to a literature procedure. Colourless crystals of the title compound suitable for X-ray diffraction were grown from a methanol solution at 253 K.

Refinement top

H atoms were located in a difference map, but refined with fixed individual displacement parameters [Uiso(H) = 1.2Ueq(Cmethylene) or Uiso(H) = 1.5Ueq(Cmethyl)] using a riding model, with C—H = 0.98 and 0.99 Å for Cmethyl and Cmethylene, respectively. In the absence of anomalous scatterers Friedel pairs were merged.

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.
