Abstract
The asymmetric unit of the title compound C14H12BrN (systematic name (E)-N-(4-bromophenyl)-1-(p-tolyl)methanimine) contains one half-molecule: a crystallographic center of inversion is located at the midpoint of the bridging N=C bond. The central HC=N unit makes dihedral angles of 15.7(3)° and 15.2(4)° with bromobenzene and methylbenzene ring systems, respectively. The C and N atoms of the HC=N central unit are disordered over two sites in a 50:50 ratio. The Br atom of the 4-bromoaniline ring and the methyl atom of the 4-methylbenzilidene ring systems are also 50% disordered. In the crystal, molecules are linked by C–H⋯π interactions forming slabs parallel to the bc plane. The atomic coordinates are not available for the previously reported crystal structure of the title compound: CSD refcode MBZCLE. The reported R factor of 0.103 for the analysis in the space group P21/a is much higher than in the present analysis, which gives 0.033 in the space group P21/c.
