Abstract:
The title compound, [Ni(C(2)H(8)NO(6)P(2))(2)(H(2)O)(2)]·9H(2)O, exhibits a slightly distorted octa-hedral coordination environment around the Ni(II) atom. It contains two mol-ecules of 1-amino--ethyl-idenediphospho-nic acid in the zwitterionic form, coord-inated via O atoms from two phospho-nate groups and creating two six-membered chelate rings. Two water mol-ecules in cis positions complete the coordination environment of the Ni(II) atom. The title compound contains nine partly disordered solvent water mol-ecules, which create a three-dimensional network of strong O-H⋯O and N-H⋯O hydrogen bonds.

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...
