Abstract:
Crystals of the title compound, C(4)H(8)N(5)+.C(2)F(3)O(2)-, are built up of singly protonated 2,4-diamino-6-methyl-1,3,5-triazin-1-ium cations and trifluoroacetate anions. The CF(3) group of the anion is disordered. The oppositely charged ions interact via almost linear N-H...O hydrogen bonds, forming a CF(3)COO-...C(4)H(8)N(5)+ unit. Two units related by an inversion centre interact through a pair of N-H...N hydrogen bonds, forming planar (CF(3)COO-...C(4)H(8)N(5)+...C(4)H(8)N(5)+.CF(3)COO-) aggregates that are linked by a pair of N-H...O hydrogen bonds into chains running along the c axis.

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...
