Concerted interaction between conjugated double bond CHs and multiple OHs in polyene macrolide antibiotic chainin: weak =C-H...O interactions responsible for intrinsic molecular assembly.
The concerted interactions observed between five conjugated double bond CHs and four hydroxy Os in the crystal of chainin, a polyene macrolide antibiotic, clarified the existence of unprecedented, weak =C-H...O interactions, which is important for forming its intrinsic molecular assembly.
