摘要: Two new polyoxometalate-templated organic–inorganic hybrid compounds with different metal–organic frameworks, [Ag5(trz)6][H4PMo12O40] (1) and [Ag10(trz)8][HPMo12O40] (2) (trz = 1,2,4-triazole), have been prepared based on the same organic ligands under pH values. Compound 1 exhibits a honeycomb 2D [Ag5(trz)6] network 3D graphite-like framework, compound 2 {Ag3[Ag6(trz)6][Ag(trz)2]} framework channels, in which [PMo12O40]3− polyanions locate center of channels. To best our knowledge, represent highest coordination number terminal oxygen Keggin POMs up to date. A comparison two demonstrates that mode 1,2,4-triazole templates important influences assembly frameworks. In addition, exhibit good photocatalytic degradation Rhodamine-B, are very stable easily recyclable as well.
