Bis[1-(isopropyl-ideneamino)guanidinium] bis-(3-nitro-benzoate) monohydrate
Abstract:
The asymmetric unit of the title salt hydrate, 2C(4)H(11)N(4) (+)·2C(7)H(4)NO(4) (-)·H(2)O, comprises two independent 1-(isopropyl-ideneamino)guanidinium cations, two independent 3-nitro-benzoate anions and a water mol-ecule of crystallization. There are minimal geometric differences between the two planar [maximum deviations 0.061 (2) and 0.088 (2) Å] cations, and between the two almost planar anions [C-C-C-O and C-C-N-O torsion angles of 0.3 (3) and 11.1 (4) °, respectively in the first anion and -173.7 (2) and -0.1 (4), respectively in the second anion]. Extensive O-H⋯O and N-H⋯O hydrogen bonding between all components of the structure leads to the formation of a two-dimensional array with an undulating topology in the bc plane.

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...
