چکیده
The asymmetric unit of the title compound, C15H15NO2, contains two independent mol-ecules (A and B). The di-methyl-phenyl ring, the phenyl ring and the central carbamate N-C(=O)-O group are not coplanar. In mol-ecule A, the di-methyl-phenyl and phenyl rings are inclined to the carbamate group mean plane by 27.71 (13) and 71.70 (4)°, respectively, and to one another by 84.53 (13)°. The corresponding dihedral angles in mol-ecule B are 34.33 (11), 66.32 (13) and 85.48 (12)°, respectively. In the crystal, the A and B mol-ecules are arranged alternately linked through N-H⋯O(carbon-yl) hydrogen bonds, forming -A-B-A-B- chains, which extend along [100]. Within the chains and linking neighbouring chains there are C-H⋯π inter-actions present, forming columns along the a-axis direction. The columns are linked by offset π-π stacking inter-actions, forming a three-dimensional network [shortest centroid-centroid distance = 3.606 (1) Å].

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...
