Crystal structure of phenyl N-(4-nitrophenyl)carbamate

The asymmetric unit of the title compound, C13H10N2O4, contains two independent molecules (A and B). The dihedral angle between the aromatic rings is 48.18 (14)degrees in molecule A and 45.81 (14)degrees in molecule B. The mean plane of the carbamate N-C(=O)-O group is twisted slightly from the attached benzene and phenyl rings, making respective dihedral angles of 12.97 (13) and 60.93 (14) in A, and 23.11 (14) and 59.10 (14)degrees in B. In the crystal, A and B molecules are arranged alternately through N-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi interactions, forming chains along the a axis. The chains are further linked by C-H center dot center dot center dot O hydrogen bonds into a double-chain structure.
