Study on structure of few sulphur containing 1,4-naphthoquinone derivatives

Structures of two polymorphs in 1,3-propaneditholate bridged di-2-methyl-1,4-naphthoquinone differs in the weak C–H···O interactions. The structures of two other derivatives having 1,3-ditholatobenzene bridge and two units of S–S bond 1,2-ditholatobenzene bridged di-2-methyl-1,4-naphthoquinone are determined. The S–π interactions are observed in one of these compounds.
