Two Cd(II) Coordination Compounds Based on the Flexible N-Bridging Ligands: Syntheses, Crystal Structures and Luminescent Properties

Two coordination compounds, Cd2(Рtt)2Cl4(H2O)2 (Ι) and [Cd(Dpb)2Cl2]n · nH2O (II) (Рtt = 3-(pyrid-2-yl)-5-(1H-1,2,4-triazol-3-yl)-1,2,4-triazolyl), Dpb = 1,4-bis(pyridin-3-ylmethoxy)benzene), were synthesized from hydro-solvothermal technique. Their structures have been characterized by infrared spectra, elemental analyses, single crystal X-ray diffraction analyses (CIF files CCDC nos. 1903141 (Ι), 1903138 (II)) and thermogravimetric analyses. Compound Ι is a dinuclear structure and II is a 1D chain. Moreover, the luminescent properties of Ι and II have been investigated with fluorescent spectra in the solid state, the two compounds display a strong fluorescent emission at room temperature and have potential applications as fluorescent-emitting materials.
