The single-crystal structure of the 1:1 HNS-dioxan adduct has been determined. The HNS and dioxan molecules form zigzag chains, which then stack to form sheets. The removal of the dioxan by heating results in the formation of crystalline, desolvated HNS, while the reintroduction of vapor-phase dioxan restores the original HNS-dioxan structure.
