In the title compound, C27H21N3O2·2H2O, the three benzene rings attached to the heterocyclic imidazole ring are not coplanar with the latter, making dihedral angles of 14.8 (2), 31.4 (2), and 37.5 (2)°, respectively, for the benzene ring planes in the 2-, 4- and 5-positions. In the crystal, there are two water molecules which serve as connectors between the acrylate molecules and stabilize the structure via N—H⋯O, O—H⋯N, C—H⋯O and O—H⋯O hydrogen bonding.

The title compound was prepared as reported earlier (Liu et al., 2006). A mixture of 4-(4,5-diphenyl-1H-imidazol-2-yl)benzaldehyde (0.225 g, 0.69 mmol), ethyl 2-cyanoacetate (0.156 g, 2.1 mmol) and pyridine (2 ml) was stirred at room temperature for 10 h. The solution was poured into water (15 ml) and orange precipitate of the title compound formed immediately. The precipitate obtained was filtered, washed with water and dried. Single crystals of the title compound were obtained by slow evaporation from ethyl acetate at room temperature.
The H-atoms bonded to N and water molecules were located from a difference map and were included at restrained distances O—H = 0.82 (2) and N—H = 0.86 (2) Å. The rest of the H atoms were positioned in calculated positions with C—H = 0.93, 0.96 and 0.97 Å for aryl, methyl and methylene type H-atoms and were refined using a riding model, with Uiso(H) = 1.5 Ueq(C) for methyl H atoms and Uiso = 1.2Ueq for others.

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. |

2,4,5-Triarylimidazoles based on extended organic π systems have received increasing interest due to the intriguing electronic and photophysical properties (Valiyev et al., 2007). As part of our on-going research interest in chemiluminescence compounds, the title compound was synthesized and its crystal structure determined as described herein.
The molecular structure of the title compound is presented in Fig. 1. Three benzene rings attached to the heterocyclic imidazole ring are not coplanar with the latter, with dihedral angles of 14.8 (2)°, 31.4 (2)°, and 37.5 (2)°, respectively, between the benzene ring planes in the 2-, 4- and 5-positions of the imidazole ring.
In the crystal packing, H2O molecules serve as connectors to form the three-dimensional packing via hydrogen bonds (Fig. 2, Tab. 1), including N—H···O, O—H···N, C—H···O and O—H···O hydrogen bonds.
The crystal structures of several compounds related to the title molecule have been reported (Fridman et al., 2009).
