Structure and electrochemical studies on the complexation of hexacyclohexanocucurbit[6]uril with lead ion

Abstract A new supramolecular complex [Pb 2 (C 60 H 72 N 24 O 12 )Cl(NO 3 ) 3 (H 2 O) 3 ] 2 ( 1 ) has been synthesized through slow evaporation of the volatiles in air at room temperature from a mixed solution of Cy 6 Q[6] and Pb(NO 3 ) 2 . The interaction between Cy 6 Q[6] and Pb 2+ cation has been studied by single crystal X-ray diffraction studies in the solid state and by electrochemical analysis in aqueous solution. Experimental results showed the ratio of Cy 6 Q[6] and Pb 2+ in complex 1 to be 1:2.
