Synthesis, crystal structure and characterization of lead(II) coordination polymers with tetrafluorosuccinate/hexafluoroglutarate

Two complexes, [Pb(TFSA)(phen)]n (1) and [Pb(HFGA)(phen)]n (2) (TFSA = tetrafluorosuccinate, HFGA = hexafluoroglutarate, and phen = 1,10-phenanthroline) have been synthesized and structurally characterized by single-crystal X-ray diffraction. The 1 shows that the 2-D structure with six normal Pb-ligand bonds and one weak Pb⋯O bond, and then is further connected by C-H⋯O and C-H⋯F hydrogen bonds, forming a 3-D network. The 2 has 1-D structure with four normal Pb-ligand bonds that further produces a 3-D network by C-H⋯O, C-H⋯F hydrogen bonds, and weak Pb⋯O bonds. The two complexes display high thermal stability and luminescent properties.
