Metal Adducts of Diselenium Dinitride

Abstract

Adducts of diselenium dinitride, a species as yet unknown in the free state, may be prepared with either palladium or aluminium as the metal centre. Thus salts of [Pd₂X₆]^2- (X = CI or Br) react with Se₄N₄ at 100°C in CH₂Cl₂ to give [Pd₂X₆(Se₂N₂)]^2- while A1X₃ reacts with the same reagent, at ambient temperatures in CH₂X₂, to give [(AlX₃)₂(Se₂N₂)]. When X = Cl in the latter case the product cannot be obtamed in pure crystaUine form; here we present IR data which confirms the presence of the neutral Se₂N₂ unit.
