N2 - The [{(C6H6)Ru}2W8O30(OH)2]6−hybrid (organometallic-POM) anion was used as a pH-tunable building block to create special conditions for realizing π-π interactions in the crystal structure. Changing the pH of an aqueous solution of Na6[{(C6H6)Ru}2W8O28(OH)2]·16H2O (1) results in isolation of a series of new compounds with different Na+/H+ratios in the cationic composition: Na5.5H0.5[{(C6H6)Ru}2W8O28(OH)2]·15H2O (2), Na5H[{(C6H6)Ru}2W8O28(OH)2]·22H2O (3), Na4H2[{(C6H6)Ru}2W8O28(OH)2]·24H2O (4), Na3H3[{(C6H6)Ru}2W8O28(OH)2]·23H2O (5), and NaH5[{(C6H6)Ru}2W8O28(OH)2]·9H2O (6). All complexes were characterized by single crystal X-ray diffraction (SCXRD) analysis and ICP-AES. The presence of π-π stacking was detected for moderate-to-highly protonated3-6. The energy of such interactions was calculated to increase in the following order:6(5.0 kJ mol−1) <5(7.6 kJ mol−1) <3(10.0 kJ mol−1).1was studied for its electrochemical behavior in 0.5 M Li2SO4and as a paste electrode component in methanol. Catalytic activity in methanol oxidation was detected.
