The title compound, C23H26N4O·5H2O, has noncrystallographic twofold rotation symmetry in the solid state. It crystallizes with five solvent water mol­ecules in the asymmetric unit. Four of these water mol­ecules are connected with each other via hydrogen-bonding inter­actions to form two types of centrosymmetric hexa­meric (H2O)6 rings. Via edge sharing of the hexa­mers, the water clusters thus build infinite chains that stretch parallel to the a axis. The fifth water mol­ecule provides an additional connection between the two hexa­meric (H2O)6 units via hydrogen bonds to both rings. The water mol­ecules in the channels along the a axis are also bonded via O—H⋯N hydrogen bonds to the organic units, and face-to-face π–π inter­actions [with centroid-to-centroid distances of 3.656 (1) Å and average face-to-face distances of 3.431 (5) Å] between the aromatic rings of adjacent mol­ecules complete the inter­molecular inter­actions in this structure.

Comment top

Currently there is considerable interest in the use of benzimidazole complexes to model the active site of a variety of metalloenzymes such as carbonic anhydrase and carboxypeptidase (Hay et al., 1998). In this context we prepared (Fig 4) and analyzed the title benzimidazole compound, and its structure is described here.

The title molecule (Fig 1) has non-crystallographic two fold symmetry with an r.m.s. deviation for both halves of 0.066 Å. It crystallizes with five lattice water molecules in the asymmetric part of the unit cell. Four of these water molecules (O1W, O2W, O3W and O5W) are connected with each other via hydrogen bonding interactions to form two types of centrosymmetric hexameric (H2O)6 rings. Via edge sharing of the hexamers the water clusters thus build infinite chains that stretch parallel to the a axis. The fifth water molecule O4W provides an additional connection between the two hexameric (H2O)6 rings via hydrogen bonds to both units. Water molecules O1W and O5W in the channels along a axis are also bonded via O—H···N hydrogen bonds to N4 and N1 of the organic unit, and all water molecules act both as donors and acceptors (Fig. 2).

Face-to-face π-π interactions between adjacent benzimidazoles made up by the atoms C1—C7, N3 and N4 and their symmetry equivalents at 1 - x, -y, 2 - z (with centroid-to-centriod distances of 3.656 (1) Å and an average face-to-face distance of 3.431 (5) Å, Fig. 3) complete the intermolecular interactions in this structure and lead to the formation of a 1-D supramolecuar chain along the a axis.

Experimental top

To a solution of 1,7-dichloro-4-oxoheptane (8.3 g, 47 mmol) and ethylene glycol (2.9 g, 47 mmol) in cyclohexane (35 ml) was added 0.024 g sodium bisulfate. The reaction mixture was refluxed for 3 h with azeotropic removal of water via a Dean–Stark trap, until there was no more water created. The resulting clear solution was cooled down, washed with water twice, and then distilled. The fraction distilling between 447 K and 453 K was collected to obtain 1,11-dichloro-(5,8-dioxaspiro[4.2]undecane) as a clear liquid (5.5 g, 25 mmol, 53%).

A mixture of 2-methyl-benzimidazole (6.6 g, 50 mmol) and NaOH (2.0 g, 50 mmol) in DMSO (10 ml) was stirred at 333 K for 1 h, and then the collected distillate (5.5 g, 25 mmol) from the previous step was added. The mixture was cooled to room temperature after stirring at 333 K for 2 h, then poured into 200 ml of water and a white solid formed immediately. The compound (5,8-dioxaspiro[4.2]undecyl)bis(2-methyl-benzimidazole) was obtained in 74% yield (7.6 g, 19 mmol).

After washing with 50 ml water, the solid was transfered into 150 ml water with 10 ml HCl (12 mol l-1). The mixture was refluxed for 3.5 h, and then filtered. The obtained residue was dissolved in 100 ml me thanol, and colorless single crystals of the title compound were obtained after several days at room temperature (3.7 g, 10 mmol, 55%).

Refinement top

The methyl H atoms were refined as members of rigid groups with C—H = 0.96 Å and Uiso(H) = 1.5Ueq(parent atom), and were allowed to rotate around the C—C bonds. Other H atoms on C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(parent atom). Water H atoms were located in a difference Fourier map and refined as riding atoms, with an O—H distance of 0.89 (2) Å, and with Uiso(H) = 1.5Ueq(O). An anti-bumping restraint (standard deviation 0.01 Å) was used to avoid chemically not meaningful close contacts between the hydrogen atoms of the water molecules.

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.
