3 Details of X-ray crystallography. Diffraction measurements for 1t OTf, 2d PF 6, and 3 W 6 O 19 were made on Rigaku MicroMax-007 with Mo Kα radiation (λ = Å). The data collections were carried out at 153 K. Indexing was performed from 12 oscillation images, which were exposed for 5 s. The crystal-to-detector distance was 45 mm. Readout was performed with the pixel size of mm. A sweep of data was done using ω scans from 110 to 70 at κ = 45 and φ = 0, 90. A total of 720 images for each compound were collected. Neutral scattering factors were obtained from the standard source. 1 Data were corrected for Lorentz and polarization effects. Empirical absorption corrections were made with HKL 2000 for Linux. 2 Molecular structures were solved by SHELX-97 3 linked to Win-GX for Windows 4. Total of six and four anions for 1t OTf and 2d PF 6 were confirmed, but highly disordered. Therefore, the SQUEEZE program of PLATON was used to remove the electron density on the Fourier map derived from the disordered solvents of crystallization. 5 Cationic parts for 1t OTf, 2d PF 6, and 3 W 6 O 19 were refined anisotropically. Tungsten atoms of hexatungstate in 3 W 6 O 19 were refined anisotropically, whereas oxygen atoms of hexatungstate in 3 W 6 O 19 were refined isotropically. Hydrogen atoms for 1t OTf, 2d PF 6, and 3 W 6 O 19 were refined as a riding model. As for 3 W 6 O 19, parts of phenyl groups of dppe ligand in 3 W 6 O 19 were disordered. The disordered atom sets were (C21A C26A, C21B C26B) and (C61A C66A, C61B C66B), and the respective occupancies were 0.51, 0.49) and (0.39, 0.61), respectively. Hydrogen atoms for these parts were not refined. Crystallographic data for compounds 1t OTf (CCDC ), 2d PF 6 (CCDC ), and 3 W 6 O 19 (CCDC ) are available free of charge from the Cambridge Crystallographic Data Center. S3

4 Details of DFT calculations DFT calculations were performed with Gaussian 09 software. Cationic parts of 1t OTf and 2h PF 6 were optimized using 6-31G* (C, H, N) /LanL2DZ (Pd) (6D, 7F) with B3LYP level of theory, taking into account the solvation in DMSO with the conductor-like polarizable continuum model (IEFPCM) with the parameter sets of United Atom Topological Model (UAKS). The corresponding single-point energy calculation was carried out using G** (C, H, N) / LanL2DZ (Pd) basis sets with B3LYP level of theory, taking into account the solvation in DMSO with the conductor-like polarizable continuum model (IEFPCM) with the parameter sets of United Atom Topological Model (UAKS).
