1,1′-(2,5-Dimethyl­thio­phene-3,4-di­yl)diethanone

The title compound, C(10)H(12)O(2)S, crystallizes with four mol­ecules in the asymmetric unit. The main conformational difference between these mol­ecules is the orientation of the acetyl groups with respect to the ring. Whereas one acetyl group is only slightly twisted with respect to the thio­phen...

description The title compound, C(10)H(12)O(2)S, crystallizes with four mol­ecules in the asymmetric unit. The main conformational difference between these mol­ecules is the orientation of the acetyl groups with respect to the ring. Whereas one acetyl group is only slightly twisted with respect to the thio­phene ring [C—C—C—O torsion angles = 165.7 (4), −164.6 (4), 164.3 (4) and −163.6 (4)°], the other acetyl group is markly twisted out of the ring plane [C—C—C—O torsion angles = −61.2 (6), 61.3 (7), −59.7 (7) and 59.9 (6)°]. In the crystal, mol­ecules are linked by weak C—H⋯O inter­actions into infinite chains along the c axis.
