Abstract
The title compound, C31H30N2S2O6, possesses crystallographically imposed twofold symmetry with the two C atoms of the central benzene ring and the C atom of its methyl substituent lying on the twofold rotation axis. The two dansyl groups are twisted away from the plane of methyl-phenyl bridging unit in opposite directions. The three-dimensional arrangement in the crystal is mainly stabilized by weak hydrogen bonds between the sulfonyl oxygen atoms and the hydrogen atoms from the N-methyl groups. Stacking of the dansyl group is not observed. From the DFT calculations, the HOMO-LUMO energy gap was found to be 2.99 eV and indicates n→π* and π→π* transitions within the mol-ecule.

Summary
Dansyl probes play important roles in many fields, including their use as industrial tracers and labelled biological tags (Tondi et al, 2005; Li et al, 2006; Liu et al, 2016). Modified oligonucleotides that contain a dansyl fluorophore and (S)-2, 3-dihydroxy propyl carbamates linked to guanine residues result in an enhancement of the fluorescence. Such modified oligonucleotides can be used to prepare and detect the sequence of fluorogenic probes in DNA (Suzuki et al, 2013). Cu-labelled dansyl molecules have been designed and synthesized as fluorescence probes for membrane tags on apoptosis cells. These compounds can be used for PET imaging of the apoptosis in vivo (Han et al, 2016). Symmetry codes: (i) x þ 12; y þ 12; z; (ii) x; Ày þ 1; z À 12; (iii) x þ 12; y À 12; z
