(Received 15 September 2008; accepted 25 September 2008; online 18 October 2008)

The title compound, C₂₅H₃₀N₄²⁺·2Br⁻·H₂O, was synthesized from 1,1′-propylenedibenzimidazole and (E)-1-bromobut-2-ene in dimethylformamide solution. The two benzimidazole ring systems are essentially planar, with maximum deviations of 0.011 (4) and 0.023 (3) Å. The dihedral angle between these two ring systems is 25.87 (15)°. The crystal structure is stabilized by intermolecular O—H⋯Br and C—H⋯Br hydrogen-bonding interactions. Atmospheric water was incorporated into the crystal structure.

Comment top

In the light of the general importance of benzimidazole compounds, the study of bisbenzimidazoles and their related derivatives has remained an active area of research despite extensive investigation. They are present in various naturally occurring drugs such as omeprazole, astemizole and emedastine difumarate (Sakai et al., 1989). Substituted benzimidazole compounds are established pharmacophores in parasitic chemotheraphy. They also show antiviral (Tidwell et al., 1993), antimicrobial (Küçükbay et al., 1995; Küçükbay et al., 2001), antitumor (Turner and Denny, 1996), antihistaminic, anticoagulant and anti-inflammatory activities (Hall et al., 1998). The objective of this study was to elucidate the crystal structure of the title compound (I) and to compare the results obtained with our previous studies on related bis-benzimidazole compounds (Öztürk et al., 2003; Akkurt et al., 2003; Akkurt et al., 2006).

In (I) (Fig. 1), the bond lengths and angles are generally within normal ranges (Allen et al., 1987). The two benzimidazole ring systems of (I), A (N1/N2/C5–C11) and B (N3/N4/C15–C21), are essentially planar, with maximum deviations of 0.011 (4) Å for C10 and -0.10 (5) Å for C11 in A, and 0.023 (3) Å for N3 and 0.016 (5) Å for C19 in B. The dihedral angle between these two ring systems A and B is 25.87 (15) °. This angle is 31.84 (11)° in 3,30-bis(cyclohexylmethyl)- 1,10-propylenedibenzimidazolium dibromide monohydrate (Akkurt et al., 2006) and 88.42 (4)° in 3,30-bis(3- cyanopropyl)-1,10-propylene- di(benzimidazolium) dichloride dihydrate (Akkurt et al., 2003). This divergence may be due to the interactions of the different substituents bounded to the benzimidazole ring system.

The crystal structure of (I) is stabilized by inter and intramolecular O—H···Br and C—H···Br hydrogen bonding interactions, involving the H atoms of the water molecule (Table 1 and Fig. 2).

Experimental top

A mixture of 1,1'-propylenedibenzimidazole (0.9 g, 3.26 mmol) and (E)-1-bromobut-2-ene (1.2 g, 6.78 mmol) in dimethylformamide (5 ml) was heated under reflux for 3 h. The mixture was then cooled and the volatiles were removed in vacuo. The residue was crystallized from a DMF/EtOH (1:3) mixture [Yield: 1.39 g, 78%. Mp. 479–481°K].

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F² for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The observed criterion of F² > σ(F²) is used only for calculating -R-factor-obs 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.
