Synthesis, Crystal Structure, and Luminescent Properties of Two ZnII/CdII Coordination Polymers Based on 1,4-Bis(pyridine-3-Ylmethoxy)benzene

Abstract

Two polymeric frameworks, [Zn(Dpb)(Oba)]_n (Ι) and [Cd(Dpb)(2,6-Pda)H₂O]_n · nH₂O (II) (Dpb = 1,4-bis(pyridin-3-ylmethoxy)benzene, H₂Oba = 4,4'-oxybis(benzoic acid), 2,6-H₂Pda = 2,6-pyridyl-dicarboxylate), have been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction method (CIF files CCDC 1488269 (Ι), 1488270 (II)). Complex Ι is a 2D layer structure, which is constructed from 1D double chain. Complex II is a 1D chain. The luminescent properties of Ι, II have been investigated with fluorescent spectra in the solid state, I and II displayed a strong fluorescent emission at room temperature.
