Two three-dimensional coordination polymers of lead(II) with iminodiacetate and naphthalene-dicarboxylate anions: Synthesis, characterization and luminescence behavior

Lead(II) coordination polymers based on rigid-flexible 3,5-bis-oxyacetate-benzoic acid: Structural transition driven by temperature control

“…As a good tripodal ligand with two highly flexible arms and one rigid carboxyl group, 3,5-bis-oxyacetate-benzoic acid (H 3 BOABA), has not been well explored to date [17][18][19][20][21][22], especially in the presence of Pb(II) as the center ion. Pb(II) complexes, a subfamily of CPs, are excellent candidates as photoluminescence materials because their large ionic radius of lead(II) induces a wide range of coordination numbers and the presence of 6s 2 outer electrons [23][24][25]. Hence, we selected H 3 BOABA as the primary ligand and adopted the "temperature control" strategy to construct Pb(II) CPs, and three new complexes were obtained.…”
