A porous metal-organic framework (MOF) with unusual 2D→3D polycatenation based on honeycomb layers

A novel mixed-ligand 3D metal-organic framework (MOF), {Zn-2(TMTA)(bipy)(0.5)(H2O)(2)center dot NO3 center dot 2DMF center dot H2O}(n) (1) (H(3)TMTA = 4,4 ',4 ''-(2,4,6-trimethylbenzene-1,3,5-triyl)tribenzoic acid, bipy = 4,4 '-bipyridine, DMF = dimethylformamide), was constructed based on bipy-pillared honeycomb bilayers and showed the unusual 2D -> 3D polycatenation of bilayers.
