2-Imino-3-(2-nitro-phen-yl)-1,3-thia-zolidin-4-one
Abstract:
In the title compound, C(9)H(7)N(3)O(3)S, the nitro and thia-zolidinone moieties are inclined with respect to the aromatic ring at dihedral angles of 9.57 (16) and 78.42 (4)°, respectively. In the crystal, N-H⋯O hydrogen bonding connects the mol-ecules along the c and a axes to form a two-dimensional polymeric network. A weak S⋯O inter-action [3.2443 (11) Å] and phenyl ring to phenyl ring off-set π⋯π stacking [with centroid-centroid separation of 3.6890 (7) Å and ring slippage of 1.479 Å] link the polymeric chains along the b and a axes, respectively.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
