In the title compound, C10H8N6·2H2O, the central aromatic ring makes dihedral angles of 23.59 (15) and 16.99 (16)° with the terminal imidazole and tetrazole rings, respectively, which are themselves almost coplanar [dihedral angle = 6.61 (18)°]. Two H atoms of the two water molecules are half occupied. In the crystal packing, weak intermolecular O—H⋯N, O—H⋯O and N—H⋯N hydrogen bonds and π–π stacking interactions [centroid–centroid distances of 3.73 (4) Å between benzene rings and 3.66 (3) Å between imidazole and tetrazole rings] are observed.

1-tetrazole-4-imidazole-benzene(0.1 g, 0.4 mmol) was dissolved in ethonal (20 ml) and the solution was left to evaporate slowly at room temperature. After a week, colourless crystals suitable for X-ray analysis were obtained.
Carboxyl H atoms were located in a difference map but were refined as riding on the parent O atoms with O—H = 0.82 Å and Uiso(H) = 1.5 Ueq(O). Carbon and nitrogen bound H atoms were placed at calculated positions and were treated as riding on the parent C or N atoms with C—H = 0.96 (methyl), 0.97 (methylene) and N—H = 0.86 Å, Uiso(H) = 1.2 or 1.5 Ueq(C, N). H atoms of the water molecule were located in a difference Fourier map and refined as riding with an O—H distance restraint of 0.84 (1) Å, with Uiso(H) = 1.5 Ueq. two hydgrogen atoms from two water molecules are half ocuppied and split into two atoms, 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. |

Imidazole derivatives possessing the biologically important imdidazole ring, have been studied in terms of their biological activities (Reichardt et al., 1992). Inspired by this, we focus on the studies of imidazole derivatives Recently, we have obtain a new crystal structure of imidazole derivative (1-tetrazole-4-imidazole-benzene), which is crystallized by the slow evaporation of ethonal sovlent at room temperaure.
As shown in Fig.1, the title molecule crystallizes as a neutral, with two terminal imidazole and tetrazole rings almost coplanar with the dihedral angle of 6.61 (18) °. They makes dihedral angles of 23.59 (15) ° and 16.99 (16) ° with the central aromatic ring. It is noted that there are two types of π-π stacking interactions: one occurs between parallel benzene rings with centroid-centroid distances of 3.73 (4) Å; the other occurs between the imidazole and tetrazole rings with centroid-centroid distances of 3.66 (3) Å. Thus, A wide range of hydrogen bonds (O—H···N, O—H···O and N—H···N) and π-π stacking interactions contribute to the formation of the supramolecular network.
