Abstract

The azide complex [Na(15-crown-5)]₂[L(N₃) ₂] has been synthesized. X-ray single-crystal diffraction analysis revealed that two orthogonally oriented azide anions are encapsulated in one receptor, each by two opposite urea edges of the square tetreurea ligand through N_(urea) - H-N_(azide) hydrogen bonding. UV-vis titration confirmed the 1:2 (host/guest) binding mode in solution with slight bathochromic shifts compared to the ligand.
