Guest‐Dependent Flexible Coordination Networks with Fluorinated Ligands

Guest‐dependent flexible coordination networks are formed from 1,4‐bis(4‐pyridylmethyl)tetrafluorobenzene (bpf), 4,4′‐bis(4‐pyridylmethyl)octafluorobiphenyl (bpfb), 2,6‐bis(4‐pyridylmethyl)hexafluoronaphthalene (2,6‐bpfn), and 2,7‐bis(4‐pyridylmethyl)hexafluoronaphthalene (2,7‐bpfn) with Cd(NO 3 ) 2 in the presence of various organic compounds. The reaction of bpf affords one‐dimensional cyclic chains, two‐dimensional rhombus grid sheets, and three‐dimensional diamond frameworks with threefold interpenetration. The reaction of bpfb mainly affords two‐dimensional rhombus grid sheets with twofold parallel interpenetration. The reaction of 2,6‐bpfn affords a one‐dimensional ladder and two‐dimensional rhombus grid, twisted grid, and herringbone sheets. The reaction of 2,7‐bpfn affords two‐dimensional rhombus grid sheets and grid sheets with dumbbell‐shaped cavities. This diversity of network topologies is induced by interactions between the guest molecules and the flexible ligand frameworks.
