In the title molecule, C15H15N3O2S, the dihedral angle between the naphthalene ring system and the imidazole ring is 86.1 (2)°. In the weak intermolecular C—H⋯O and C—H⋯N hydrogen bonds, as well as weak C—H⋯π interactions, connect molecules, forming a two-dimensional network.

Compound (I) was synthesized according to a literature procedure (Hilderbrand et al., 2004). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethyl acetate solution of (I) at room temperature.
All H atoms were placed in idealized positions [C—H(methyl)=0.98 Å and C—H(aromatic) =0.95 Å] and included in the
in the riding-model approximation, with Uiso(Hmethyl)= 1.5Ueq(C) and Uiso(Haromatic) = 1.2Ueq(C).Data collection: SMART (Bruker, 2007); cell

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. |

Dansyl chloride is widely used as a fluorescent label in immunofluorescence methods and in yielding fluorescent N-terminal amino acids and peptide derivatives. Some dansyl chloride derivatives are also used as fluorescent probes, which can detect trace metal ions such as Pb2+, Cu2+, Zn2+ (Koike et al., 1996; Corradini et al., 1997; Kavallieratos et al., 2005). We are interested in preparing fluorescent drug or ligand analogs that are expected to bind to hydrophobic sites in proteins or membranes. With this mind, the title compound, (I), was prepared and we report the crystal stucture herein.
In the molecular structure (Fig. 1), the dihedral angle between the naphthalene ring and the imidazole ring is 86.1 (2)°. All bond lengths and bond angles are as expected. In the crystal structure (Fig.2), the molecules are linked by C–H···O and C—H···N hydrogen bonds (Table 1) and C—H···π interactions into a two-dimension network.
