Abstract:
In the mol-ecule of the title compound, C(6)H(9)N(3)O(3)S, 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 inter-molecular C-H⋯O=C and C-H⋯O=S contacts less than 2.6 Å, as well as a weak C-H⋯N=N inter-action to the diazo group.
