摘要

The first supramolecular adduct (H3O)2[Cu(H2O)4](SO4)2·2(C30H30N20O10)·24(H2O) based on cucurbit[5]uril was synthesized and characterized by single crystal X-ray diffraction analysis. In the adduct, copper ion is coordinated by four oxygen atoms from H2O. The latter links two cucurbit[5]uril molecules due to a complicated hydrogen bonding containing lattice water molecules.
