 Novel multi-chalcogen ring systems with three different chalcogen atoms:
 synthesis, structure and redox property of five-membered
 trichalcogenaheterocyclesElectronic supplementary information (ESI)
 available: satisfactory characterizing data for all the new compounds.
 Typical experimental procedure, physical and spectroscopic data of all
 the new compounds and ORTEP view of 2d. See

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 1/[\s^2^(Fo) +
0.00006|Fo|^2^]' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w = 1/[\s^2^(Fo) + 0.00006|Fo|^2^]'.
