Abstract

The possibility of using salts of 2,4,6-triamine-1,3,5-triazine, 2,4-diamine-6-methyl-1,3,5-triazine, and 2,4-diamine-6-phenyl-1,3,5-triazine for isolation of the dodecahydro-closo-dodecaborate anion [B₁₂H₁₂]^2– from aqueous solutions has been studied. Compound [2,4-(NH₂)₂-6-Ph-1,3,5-N₃С₃H]₂[B₁₂H₁₂]⋅H₂O (solubility 0.06 g in 100 g water at 17°C), promising for the precipitation of the [B₁₂H₁₂]^2– anion, has been isolated by the metathesis reaction of moderately soluble hydrochloride [2,4-(NH₂)₂-6-Ph-1,3,5-N₃С₃H]Cl⋅H₂O with sodium and potassium dodecahydro-closo-dodecaborates. A procedure has been developed for the decomposition of [2,4-(NH₂)₂-6-Ph-1,3,5-N₃С₃H]₂[B₁₂H₁₂]⋅H₂O with ammonium hydroxide to obtain soluble salts of the [B₁₂H₁₂]^2– anion.
