Four inorganic–organic hybrid octa-Cu cluster sandwiched polyoxotungstates (POTs), [Cu 8 (H 2 O) 2 (en) 4 (B-α-H 2 SiW 9 O 34 ) 2 ] ( 1 ), [Cu 8 (H 2 O) 2 (en) 4 (B-α-H 2 GeW 9 O 34 ) 2 ] ( 2 ), K 2 [Cu 8 (en) 4 (B-α-HSiW 9 O 34 ) 2 ]·6H 2 O ( 3 ), and K 2 [Cu 8 (en) 4 (B-α-HGeW 9 O 34 ) 2 ]·2H 2 O ( 4 ) (en = ethylenediamine), were hydrothermally made and characterized by single-crystal X-ray diffraction, infrared spectra, powder X-ray diffraction, and thermogravimetric analysis, respectively. Structure analysis reveals that the polyoxoanion of 1 / 2 is a discrete dimer built by two trivalent Keggin [B-α-XW 9 O 34 ] 10– (X = Si/Ge) fragments and one octa-Cu cluster, whereas 3 and 4 display a two-dimensional network built by octa-Cu-sandwiched POT units via substitution of coordinated water on polyanions of 1 and 2 and further expand into a three-dimensional framework via K cation bridges. Ultraviolet–visible diffuse reflectance spectra reveal that 1–4 are potential semiconductor materials. Moreover, its visible light-driven catalytic H 2 evolution activity, electrochemical properties, catalysis for oxygenation reactions of thioethers, and magnetic behaviors have been investigated in detail. |
