The title compound was synthesized by refluxing an equimolar mixture of m-terphenyldibromide (Hart & Rajakumar, 1995) and 4,4'-bipyridine in acetonitrile for 48 h, followed by column chromatography and counter-ion exchange with NH4PF6 (Rajakumar & Srinivasan, 2002). Single crystals suitable for X-ray studies were grown by vapour diffusion of diisopropyl ether into a solution of (I) in acetonitrile.
The H atoms of the tetracation were fixed geometrically and allowed to ride on the corresponding non-H atoms, with C—H distances of 0.93 or 0.96 Å, and with Uiso(H) = 1.2Ueq(C). The H atoms of the water molecules were located from a difference map and their positional parameters were refined with restraints on the O—H distances; the isotropic displacement parameters were set equal to 1.5Ueq(O). The reflection (132) was removed during refinement, as the observed and calculated structure factors showed a large disagreement. The Rint value is high (0.114), owing to the poor diffraction quality of the crystal.

Experimental. The data collection covered over a hemisphere of reciprocal space by a combination of three sets of exposures; each set had a different ϕ angle (0, 88 and 180°) for the crystal and each exposure of 30 s covered 0.3° in ω. The crystal-to-detector distance was 5 cm and the detector swing angle was −35°. Crystal decay was monitored by repeating fifty initial frames at the end of data collection and analysing the intensity of duplicate reflections, and was found to be negligible. |
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. |

4,4'-Bipyridinium-based tetracationic cyclophanes are found to be versatile macrocycles for constructing rotaxanes and catenanes (Amabilino & Stoddart, 1995). They have potential uses in resolving racemic substrates containing π-electron-rich aromatic rings (Asakawa et al., 1996) and function as non-sequence specific DNA photo cleaving agents (Lorente et al., 1999). cyclo-Bis(paraquat-m-terphenylene) is such a tetracationic cyclophane synthesized by refluxing an equimolar mixture of m-terphenyldibromide (Hart & Rajakumar, 1995) and 4,4'-bipyridine in acetonitrile for 48 h followed by column chromatography and counter-ion exchange with NH4PF6. We report here the structure of the tetracation as its tetrakis(hexafluorophophate) tetrahydrate, (I).
The asymmetric unit of (I) consists of one-half of the (C60H48N4)4+ tetracation, two PF6−anions and two water molecules. The other half of the tetracation is generated by a crystallographic inversion centre, as shown in Fig. 1. The centrosymmetric macrocyclic tetracation as a whole assumes a chair-like conformation, as seen by joining the centroids of the bridging terphenylene moieties with the four methylene C atoms. The mean planes through the terphenylene ring and bipyridinium ring are inclined by angles of 132.85 (3) and 97.45 (4)° with respect to the methylene plane. In the terphenylene system, the two outer rings are twisted from the central ring by 24.7 (1) and 18.9 (1)°. The dihedral angle between the two connected pyridinium rings is 15.2 (1)°. The macrocyclic valance angles at the methylene C atoms, C19 [110.9 (2)°] and C30 [111.8 (2)°], agree with the values reported for the pyridine-bridged phanes of 4,4'-bipyridine (Scheytza et al., 1999), but these values are larger than those reported for cyclo-bis(paraquat-p-phenylene) tetrakis(hexafluorophophate) (Odell et al., 1988). The overall dimensions of the macrocyclic tetracation are 13.23 Å between the centroids of the bonds connecting pyridinium rings and 12.86 Å between C12 and C12i [symmetry code: (i) −x, 1 − y, −z].
In the solid state, two inversion-related hexafluorophophate anions are inserted into the cavity of the centrosymmetric tetracation. The two P atoms, P1 and its centrosymmetric equivalent at (-x, 1 − y, −z), lie on the opposite sides of the methylene plane, at 0.874 (1) Å, and the distances separating them from the centroids of the bonds connecting pyridinium rings are each 3.975 Å. The other two anions lie on the opposite sides of the methylene plane at 5.133 (1) Å. The water O atoms, O1W and O2W, are located at 2.125 (3) and 1.989 (3) Å from the methylene plane. The four anions and the four water molecules are linked together by O—H···O and O—H···F hydrogen bonds to form discrete centrosymmetric units, as shown in Fig. 2. These units are linked to the macrocyclic tetracations through C—H···F hydrogen bonds (Table 2), to form a network structure. Two short intermolecular C···F contacts, C21···F4 [2.889 (3) Å] and C27···F6(-x, 1/2 + y, 1/2 − z) [2.933 (4) Å], are observed in the structure. But they are not indicative of C—H···F hydrogen bonding as the H21···F4 or H27···F6 distances are longer than the sum of the van der Waals radii.
