Their crystal structures were determined with X-ray single-crystal diffraction and CV behavior were examined. In the compounds ANA is protonated and acts as charge complement and hydrogen bond donor and acceptor. In 1 there is a supramolecular chain formed through fourfold hydrogen bonds between water molecules and SiW12 anions, and in 2 a supramolecular layer is formed by hydrogen bonds between protonated O1W molecules and PW12 anions. The protonated water molecule is identified from IR spectrum of 2.
