Abstract:
The Sn atom in the title compound, [Sn(C(7)H(7))(2)(C(5)H(5)N(2)O)Cl], shows a distorted C(2)ClNOSn trigonal-bipyramidal coordin-ation, with a Cl-Sn-O axial angle of 163.77 (3)°, but the C-Sn-C angle [141.43 (7)°] deviates from 120°. The chelating ligand exists in a zwitterionic form. Adjacent molecules are linked by an N-H(pyridinium)⋯O hydrogen bond, forming a chain running along the c axis of the orthorhombic unit cell.

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...
