2-Diazo-1-(1,1-dioxothiomorpholin-4-yl)ethanone

Abstract

In the mol­ecule of the title compound, C6H9N3O3S, at 105 K, the six-membered ring is predominantly found in the chair conformation, with 1.89 (14)% in the boat conformation. In the crystal structure, there are five inter­molecular C—H⋯O=C and C—H⋯O=S contacts less than 2.6 Å, as well as a weak C—H⋯N=N inter­action to the diazo group.
