The crystal structure of compound {3[Cd(2)(C(36)H(36)N(24)O(12))]center dot 10Cl center dot 10(H(2)O)] center dot 2Cl center dot 39(H(2)O) (1) is reported. It consists of complexes of cucurbituril and cadmium cations formed through ion-dipole interactions, in which a novel two-dimensional network is created by the complexation of cucurbituril and cadmium ions. Binding constants determined from voltammetric data indicate that Cd(2 ) has a high binding affinity for Q[6] (K(Cd2 ). = 9.95 x 109 M(-2) by CV) and forms a 2:1 (M(2) /Q[6]) complex.
