Crystal structure of ethyl 2-[2-(4-methyl­benzo­yl)-5- p-tolyl-1 H-imidazol-1-yl]acetate

Abstract

The crystal structure of ethyl 2-[2-(4-methyl­benzo­yl)-5- p-tolyl-1 H-imidazol-1-yl]acetate is stabilized by inter­molecular C—H⋯N and C—H⋯O inter­actions.

Abstract

In the title compound, C ₂₂H ₂₂N ₂O ₃, the plane of the five-membered ring is oriented at dihedral angles of 45.4 (1) and 52.5 (1)° to the phenyl rings. Furthermore, this ring makes an angle of 85.2 (2)° with the plane of the ethyl acetate substituent. The mol­ecular structure is affected by an intra­molecular C—H⋯O hydrogen bond between an H atom from the p-tolyl group and the carbonyl O atom of the acetate. The methyl group of the ethyl acetate residue is disordered over two sites with equal occupancies. The crystal structure features inter­molecular C—H⋯O and C—H⋯N inter­actions. One of the C—H⋯O hydrogen bonds forms a C(5) chain motif extending along the a axis. In addition, C—H⋯N contacts form inversion dimers with R ₂ ²(12) ring motifs, linking the imidazole ring system to the benzene ring of the p-tolyl substituent.
