Crystal structure of 1-(2,4-dimethylphenyl)-2-(4-trimethylsilyl-1H-1,2,3-triazol-1-yl)ethanone

Abstract

The asymmetric unit of the title compound, C15H21N3OSi, contains two molecules with similar conformations (r.m.s. overlay fit for the 20 non-H atoms = 0.163 Å). The dihedral angles between the planes of the 1,2,3-triazole and 2,4-dimethylbenzene rings are 27.0 (3) and 19.5 (3)°. In the crystal, molecules are linked by very weak C—H...O and C—H...N hydrogen bonds to generate [100] chains. The chains are cross-linked by C—H...π interactions.
