Abstract

The macrocyclic polyether 18-crown-6 (C₁₂H₂₄O₆) readily forms crystalline 1: 1 complexes with the adducts BF₃NH₃ and BH₃NH₃. Crystals of the solvates BF₃NH₃·C₁₂H₂₄O ₆·CH₂Cl₂ and BH₃NH₃·C₁₂H₂₄O ₆·MeOH were suitable for X-ray crystallographic investigation. In both cases, the crystal structures reveal that 18-crown-6 adopts an all-gauche conformation with pseudo D_3d symmetry in which the intermolecular N-H ⋯ O hydrogen-bonding interactions between the macrocyclic polyether and the adducts are associated directly with the triangle of oxygen atoms on the complexing face of the crown.
