Abstract

In the title bis-chalcone, C24H22O2S2, the –C(O)CH=CH–C6H4–CH=CHC(O)– portion is planar (r.m.s. deviation = 0.04 Å); one thienyl ring is aligned at 8.8 (1)° with respect to this fragment, whereas the other is aligned at 21.3 (1)°.

Partial Text

Chalcones possess anti-bacterial, anti-fungal and anti-inflammatory properties, see: Yarishkin et al. (2008 ▶); such properties are dramatically enhanced in bis-chalcones. For the crystal structures of some bis-chalcones, see: Harrison et al. (2007a ▶,b ▶,c ▶); Prajapati et al. (2008 ▶).
