The asymmetric unit of the title compound, CHNO, contains two independent mol-ecules ( and ). The di-methyl-phenyl ring, the phenyl ring and the central carbamate N-C(=O)-O group are not coplanar. In mol-ecule , 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 are 34.33 (11), 66.32 (13) and 85.48 (12)°, respectively. In the crystal, the and mol-ecules are arranged alternately linked through -⋯(carbon-yl) hydrogen bonds, forming ----- chains, which extend along [100]. Within the chains and linking neighbouring chains there are C-H⋯π inter-actions present, forming columns along the -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].
