A metal-organic framework with coordinatively unsaturated metal centers and microporous structure

A novel two dimensional porous framework [Cd-3(BTB)(2)-(DEF)(4)](n)center dot 2nDEF (1) based on {Cd-3} building blocks with bilayer honeycomb structure constructed from cadmium ion bridged honeycomb layers exhibits promising adsorption for N-2 after activation to obtain coordinatively unsaturated Cd centers, and SEM characterization demonstrates interesting microporous structure inside of the compound.
