摘要：

The three-dimensional (3D) supramolecular network structure of the guest 1,1'-(hexane-1,6-diyl)dipyridinium-4-carboxylate inner salt (HBPC) and the host cucurbit[6]uril (CB[6]) is self-assembled through an intricate array of hydrogen-bonding interactions involving the contributions of two-dimensional (2D) infinite network (COO-)(2)(H2O)(10) anion water clusters and (H2O)(2) water clusters. These water clusters are notably have the liquid-like water characteristics in the solid and are reversibly dehydrated and rehydrated, while the pseudorotaxane retains its integrity in the process, and is stable up to 390 degrees C.
