Abstract

This paper describes the X-ray crystal structure of a complex of acridino-18-crown-6 ether (S,S)-2 and sodium perchlorate. The structure shows a homodimer in the crystal and suggests the potential for bonded interactions between the monomers. The average distance of the two tricyclic units (3.49 ± 0.1 Å) may indicate a considerably strong interaction. Fluorescence titration was performed in order to determine the stoichiometry and stability constant (Ks) of the sodium ion-(S,S)-2 complex. Based on the global fitting of the fluorescence spectra, we suggest the formation of a complex with 1:1 ligand to metal ion ratio, and the logK value determined by nonlinear regression analysis was 5.23.
