(Received 14 May 2012; accepted 8 November 2012; online 5 December 2012)

In the title salt, C21H21Cl2N2O2+·NO3, the imidazole ring makes dihedral angles of 43.39 (14) and 10.9 (2)° with the 4-methyl­phenyl and 2,4-dichloro­phenyl rings, respectively. The mol­ecule adopts a Z conformation about the C=C double bond, which links the imidazole ring to the 4-methyl­phen­oxy unit via an eth­oxy chain. In the crystal, cations and anions are linked into chains by N—H⋯O and C—H⋯O hydrogen bonds.

Comment top

Azole derivatives such as Voriconazole and Ketoconazole are safe and effective antifungal agents (Jeu et al., 2003; Fromtling & Castaner,1996). As part of our studies on the synthesis of new azole derivatives, the crystal structure of the title compound was determined.

In the molecular structure of the title compound (Fig. 1) the double bond is Z configurated. In the crystal structure the anions and cations are connected via N—H···O and C—H···O hydrogen bonding (Table 1 and Fig. 2). The bond lengths and bpnd angles in the title compound agree with the corresponding bond lengths and angles reported for a closely related compound (Kurt et al., 1987).

Experimental top

1-(2,4-Dichlorophenyl)-2-(1H-imidazol-1-yl)-1-propanone (16.6 g, 0.06 mol), 30% aqueous sodium hydroxide (50 ml), toluene (100 ml) and tetrabutylammonium hydroxide (0.26g, 0.001mol) were mixed and heated to 343.15 K under vigorous stirring. 1-(2-Bromoethoxy)-4-methyl-benzene (13.3 g, 0.06 mol), dissolved in toluene (70 ml), wais instilled into the stirred and warmed solution in the course of 10 h. The mixture was stirred at room temperature, and monitored by TLC until the reaction was complete. The reaction mixture was mixed with as much water and chloroform so that the aqueous phase becomes lighter than the organic phase. Thereafter, the organic and aqueous phases were separated. The organic phase was dried with sodium sulfate. The solvents were distilled under reduced pressure. The remaining residue was a dark oil that is diluted with 100 ml ethanol and then adjusted to a pH-value of 2 by means of 65% aqueous nitric acid. The derived nitric acid solution was cooled in the refrigerator. The impure precipitated product herein was subsequently crystallized from isopropanol. The purified product was analytically identified as an approximately pure Z-isomer of propylene nitrate. Crystals of title compound suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution. Details on the synthesis can be found in the literature (Ludwig & Kurt, 1985).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
