Cd(II) coordination polymers, p-phthalic acid, Hirshfeld surface, Luminescent properties
ABSTRACT
Two new 3-D Cd(II)
coordination polymers with p-phthalic acid (p-BDC)
and 4,4?-dipyridyl-amine (4,4?-dpa), namely [Cd2(p-BDC)2(4,4?-dpa)2]n 1 and {[Cd(p-BDC)(4,4?-dpa) (H2O)]·4H2O}n 2 were successfully synthesized under hydrothermal conditions at 120 and
140 °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.
