摘要

The synthesis, structures, and quantum-chemical calculations of tri(phosphorano)borazinium ions are reported for the first time. [HBNPEt₃]₃³⁺(I^-)₃ (6) and [H₄B₃(NPEt₃)₃]²⁺(I ^-)₂ (7) originate from iodine acting on the borane adduct at trimethylsilyltriethylphosphoraneimine. With acetonitrile 6 reacts under formation of [{HBNPEt₃}₃CH₃CN]³⁺(I ^-)₃ · CH₃CN (8). While 6 forms an almost planar B₃N₃ six-membered ring with BN distances of 143 pm, which are equivalent to those in borazine molecules, in 7 and 8 one boron atom at a time is sp³ hybridized due to an additional bonding with a hydride ligand and to the adduct formation with acetonitrile, respectively. The quantum-chemical calculations suggest relatively polar B-N bonds.
