Supramolecular Two-dimensional Arrays with Phenyl/Perfluorophenyl Interactions Constructed from One-dimensional Coordination Polymers

Supramolecular assembly of Cd(NO3)2, aniline derivatives and fluorinated ligand 1,4-bis(4-pyridylmethyl)-2,3,5,6-tetrafluorobenzene (bpf) afforded one-dimensional coordination polymers [Cd(bpf)(aniline)2(NO3)2]n (1), [Cd(bpf)(p-toluidine)2(NO3)2]n (2), and {[Cd(bpf)(p-bromoaniline)2(NO3)2]·(p-bromoaniline)2}n (3). The 1D polymers of 1 and 2 were connected through phenyl/perfluorophenyl interaction to give supramolecular two-dimensional arrays while no such interaction in 3 due to the bulky Br group.
