Cation-π Interaction in complex formation between Tl+ Ion and Calix[4]crown-6 and some calix[4]biscrown-6 derivatives: Thallium-203 NMR, proton NMR, and X-ray evidence

Metallocapped complexation of the thallium(I) ion with calix[4]crown-6 (1) and three different calix[4]biscrown-6 derivatives (2-4) has been investigated by a combination of 203Tl and 1H NMR in a CD 3CN/CDCl3 (4:1 v/v) solution. The results clearly revealed the formation in solution of mono- and dithallium(I) complexes in which the metal cations are held in the ligands cavities close to the calix[4]arene ring. In addition, a solid state mononuclear complex between 1,3-calix[4]bis-o-benzo- crown-6 (3) and TlClO4 was prepared, and its X-ray crystal structure was determined. The results of the structural data in solution and the solid state suggested that the calix[4]crown-6 derivatives considered provide π cavities as active sites for the complexation of thallium(I) ions.
