Abstract

Unprecedented polyoxometalate based metal–carbene frameworks (POM-based MCFs) [Cu10(H3trz)4(Htrz)4](HPW12O40) (1) and [Cu10(H3trz)4(Htrz)4](H2SiW12O40) (2) have been fabricated via a hydrothermal reaction between 1,2,4-triazole and Cu(CH3COO)2 with the saturated Keggin polyoxoanion [PW12O40]3−/[SiW12O40]4− as a template for the first time. Single crystal X-ray diffraction analysis reveals the successful encapsulation of Keggin POMs into the three-dimensional POM-based MCFs with lvt-a topology based on their effective coordination with Cu ions. Interestingly, these novel 3D POM-based MCFs exhibit good electrochemical performance in lithium-ion batteries (LIBs) as anode materials, with first discharge capacities of ca. 1620 and 1245 mA h g−1 for 1 and 2, respectively, at a current density of 100 mA g−1, and stabilized discharge capacities of ca. 570 mA h g−1 for 1 and 426 mA h g−1 for 2 after 100 cycles. This, in combination with their high thermal stability, suggests their good LIB application potential.
