All chemicals used were purchased from Jinan Henghua Sci. & Tec. Co., Ltd. The salt was synthesized from the reaction of 1,1'-(1,4-phenylenedimethylene)dipyridinium dichloride (0.033 g, 0.1 mmol) in methanol (5 ml) and Na[BPh4] (0.034 g, 0.1 mmol) in DMF (10 ml). The mixture was set aside for the formation of colorless crystals in 54% yield after several days. Anal. Calc. for C33H29BN: C 88.00, H 6.44, N 3.11%; Found: C 87.96, H 6.47, N 3.07%.
H atoms were generated geometrically (C—H = 0.93 or 0.97 Å) and refined as riding, with Uiso(H)= 1.2Ueq(C).
The tetraphenylborate ion, BPh4-, has been widely used as a counterion in cation complex systems. These cations include metal atoms, organic ammonium cations, bipyridinium cations and arenediazonium cations (Kiviniemi et al., 2001). In our previous studies we have investigated the organo-inorganic hybrid compounds containing the 1,ω-alkylidene dipyridine cations (Liu, Liao et al., 2007; Liu, Shi et al., 2007). Herein we report the crystal structure of 1,1'-(1,4-phenylenedimethylene)dipyridinium cation with tetraphenylborate.
The asymmetric unit of the title compound (Fig. 1), (C18H18N2)0.5.B(C6H5)4, contains half a 1,1'-(1,4-phenylenedimethylene)dipyridinium cation and one tetraphenylborate anion; the cation is located on an inversion center. The cation is surrounded by four anions and interacts with three of them via C—H···π interactions (Table 1 and Fig. 2).
For related literature, see: Kiviniemi et al. (2001); Liu, Liao et al. (2007); Liu, Shi et al. (2007). Cg1, Cg2 and Cg3 are the centroids of the C16–C21, C22–C27 and C28–C33 phenyl rings, respectively.

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. |

The tetraphenylborate ion, BPh4-, has been widely used as a counterion in cation complex systems. These cations include metal atoms, organic ammonium cations, bipyridinium cations and arenediazonium cations (Kiviniemi et al., 2001). In our previous studies we have investigated the organo-inorganic hybrid compounds containing the 1,ω-alkylidene dipyridine cations (Liu, Liao et al., 2007; Liu, Shi et al., 2007). Herein we report the crystal structure of 1,1'-(1,4-phenylenedimethylene)dipyridinium cation with tetraphenylborate.
The asymmetric unit of the title compound (Fig. 1), (C18H18N2)0.5.B(C6H5)4, contains half a 1,1'-(1,4-phenylenedimethylene)dipyridinium cation and one tetraphenylborate anion; the cation is located on an inversion center. The cation is surrounded by four anions and interacts with three of them via C—H···π interactions (Table 1 and Fig. 2).
