Construction of polyoxometalates-based coordination polymers through direct incorporation between polyoxometalates and the voids in a 2D network

A series of polyoxometalates (POMs)-based coordination polymers are synthesized through direct incorporation between POMs and the voids of the two-dimensional (2D) network. The crystal structural analysis has shown that the relationship between the size of the void of the 2D network and that of POMs is very important for the synthesis of POMs-based open metal-organic frameworks.
