2,4,6-Trinitro-phenyl 4-chloro-benzoate.

ABSTRACT: In the title benzoate derivative, C13H6ClN3O8, the planes of the benzene rings form a dihedral angle of 63.46?(5)°. The dihedral angles between the benzene ring and its nitro groups are 12.78?(16)° for the first ortho, 28.4?(4) and 17.4?(4)° for the second (disordered) ortho and 3.58?(16)° for the para nitro group. The central ester moiety, -C-(C=O)-O-, is essentially planar (r.m.s. deviation for all non-H atoms = 0.0229?Å) and forms dihedral angles of 7.37?(14)° with the chloro-substituted benzene ring and 69.85?(6)° with the trinitro-substituted benzene ring. One of the nitro groups was refined as disordered over two sets of sites with fixed site occupancies of 0.61 and 0.39. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds, forming a three-dimensional network.
