Temperature-controlled Structural Diversity of Two Cd(II) Coordination Polymers Based on the Dicarboxylate Ligand

摘要

Two new 3-D Cd(II) coordination polymers with p-phthalic acid (p-BDC) and 4,4'-dipyridylamine (4,4'-dpa), namely [Cd-2(p-BDC)(2)(4,4'-dpa)(2)]n 1 and {[Cd(p-BDC)(4,4'-dpa) (H2O)]center dot 4H(2)O}n 2 were successfully synthesized under hydrothermal conditions at 120 and 140 degrees C. They were characterized by single-crystal X-ray diffraction, IR, PXRD and TGA. It was further characterized by Hirshfeld surface (HS) analysis for complex 2. The luminescent properties of the complexes have also been investigated.
