Abstract

"This structure is related to synthesis of new polythiophene derivatives. Their most interesting aspects are to be found in their interatomic interactions, of varied type (C-H ? O, C-H ? π, π ? π) and strength. In the title compound C12H10O2S there are two independent molecules per asymmetric unit but unlike the former one (where interatomic interactions do not ""mix"" them), herein both types of independent molecules are interlinked through H-bonding interactions to form broad strips along [010], four molecules in width and displaying a zig-zag pattern. These structures fit into each other along the [100] direction, in a ""gear-like"" fashion, giving raise to some π - π contacts."
