Abstract:

A new coordination polymer {[Zn2(dpb)2(bdc)2]·1.3H2O}n(1) was prepared under solvothermal condition using terephthalate(1,4-H2bdc) as well as 1,3-dipyridyl benzene(1,3-dpb) as initiators. The complex was characterized by means of infrared spectroscopy(IR), thermogravimetric analysis(TGA), powder X-ray diffraction(XRD) and X-ray single-crystal diffraction. The results indicate that complex 1 crystallizes in the monoclinic system with space group of P21/c. The neighboring Zn(II) ions are linked by ligand dpb to form infinitely meso-helical or zigzag chains, which are further connected to form a two-fold interpenetrated 3D framework, in which there exists strong hydrogen bonds(O-H…O) between the interpenetrated frameworks. In addition, the solid-state fluorescence behavior of complex 1 was also discussed.
