Abstract:
The Pd(II) ion in the title complex, [PdI(2)(C(14)H(10)N(4))], is four-coordinated in a slightly distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two iodide anions. In the crystal, the pyridine rings are considerably inclined to the least-squares plane of the PdI(2)N(2) unit [maximum deviation = 0.090 (2) Å], making dihedral angles of 65.0 (2) and 66.6 (2)°. The pyrazine ring is perpendicular to the unit plane, with a dihedral angle of 89.9 (2)°. The complex mol-ecules are connected by C-H⋯I hydrogen bonds, forming a helical chain along the b axis.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
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...
