Abstract

This paper describes the X-ray crystal structure of a complex of acridono-18-crown-6 ether 3 and lead(II) perchlorate. The structure shows a π-π bonded heterodimer in the crystal. One part of the dimer moves to 9-hydroxyacridine tautomeric form upon lead(II) complexation, in which the lead(II) ion is eight-coordinated and fits well into the cavity of the macrocycle. The other part of the dimer stays in the 9(10H)-acridone tautomeric form, which favors water complexation. The average bond distance of the two tricyclic units (3.5 Å) indicates a strong π-π interaction. The X-ray studies also revealed a cation-π interaction between lead(II) and the electron-rich acridone moiety.
