3,12-Diaza-6,9-diazo-nia-2,13-dioxotetra-decane bis-(perchlorate)
Abstract:
The crystal structure of the title diprotonated diacetyl-triethyl-ene-tetra-mine (DAT) perchorate salt, C(10)H(24)N(4)O(2) (2+)·2ClO(4) (-), can be described as a three-dimensional assembly of alternating layers consisting of diprotonated diacetyl-triethyl-ene-tetra-mine (H(2)DAT)(2+) strands along [100] and the anionic species ClO(4) (-). The (H(2)DAT)(2+) cations in the strands are connected via N-H⋯O hydrogen bonding between the acetyl groups and the amine groups of neighbouring (H(2)DAT)(2+) cations. Layers of (H(2)DAT)(2+) strands and perchlorate anions are connected by a network of hydrogen bonds between the NH and NH(2) groups and the O atoms of the perchlorate anion. The asymmetric unit consits of one perchlorate anion in a general position, as well as of one cation that is located on a center of inversion.

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...
