Interpenetrating coordination polymers from Cu(I) or Ag(I) and flexible ligands: 2D polyrotaxanes and interpenetrating grids.
The reaction of [Cu(CH3CN)4]NO3 or AgNO3 with flexible ligands 1,4-bis(4-pyridylmethyl)-2,3,5,6-tetrafluorobenzene (bpf) or 4,4'-bis(4-pyridylmethyl)-2,2',3,3',5,5',6,6'-octafluorobiphenyl (bpfb) afforded two types of interpenetrating coordination polymers. The structures of [Cu2(bpf)3(NO3)2]n and [Ag2(bpf)3-(NO3)2]n are 2D polyrotaxane networks in which 1D polymeric chains are aligned in a grid. The structure of {[Cu(bpfb)2]NO3}n is a 2D grid polymer with two-fold parallel interpenetration.
