Syntheses, Crystal Structures, and Luminescent Properties of Zn-II/Cd-II Coordination Polymers with Different Interpenetrating Networks

摘要

Zn-II and Cdu coordination polymers with dicarboxylate and imidazole-containing Ligands, namely, [Cd (2,3-PDC)(L)(n) (1) and {[Zn(3,4-PDC) (L)(0.5)]center dot H2O), (2), [2,3-H2PDC = 2,3 pyridine dicarboxylate, 3,4-H2PDC = 3,4-pyridine dicarboxylate, and L = 1,4 bist2 methylimidazol-3-ium-1-yl)biphenyl], were prepared and charactetized by elemental analysis, IR spectroscopy, and X-ray diffraction. Complex 1. shows a three-dimensional (3D) structure with threefold interpenetrating diamond topology. Complex 2 features a 3D framework with twofold interpenetrating dmc topology. Moreover, the luminescent properties of complexes 1 and 2 were also investigated.
