Description:
Two polyoxometalate-based compounds constructed by Keggin/Ag/ L , namely [Ag 10 ( L 1 ) 6 (H L 1 ) 2 ][HPMo 2 V Mo VI 10 O 40 ] ( 1 ) and [Ag 10 ( L 2 ) 8 (H 2 SiMo 12 O 40 )] ( 2 ) ( L 1 = 1,2,4-1H-triazole and L 2 = 1H-tetrazole), were synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analyses, and IR spectroscopy. In compound 1 , the tetra-nuclear Ag cycles constructed by four L 1 ligands, two Ag1 ions, and two Ag2 ions. Compound 1 exhibits a two dimensional (2D) metal-organic layer containing adjacent tetra-nuclear Ag cycles. Furthermore, the adjacent 2D layers are further extended by Ag ions to form a three dimensional (3D) channel-like framework, with Keggin anions embedding in the channels. Compound 2 is isostructural with 1 . Additionally, the electrochemical and photocatalytic properties of the title compounds were investigated.
