organic compounds
In 2,6-dimethylphenyl 4-nitrophenyl sulfone, C14H13NO4S (I), 2,6-dimethylphenyl 4-methylphenyl sulfone, C15H16O2S (II), and 2-methylphenyl phenyl sulfone, C13H12O2S (III), the S atoms have distorted tetrahedral bonding geometry. In each compound, the phenyl rings are nearly perpendicular to each other [dihedral angles: 80.0 (1) in (I), 89.6 (1) in (II), and 78.9 (1)° in (III)].
