| Abstract: The ligand N,N'-bis((2'-pyridyl)methylene)pyridine-3,5-dicarbohydrazide(bpmphz, 1), and its Zinc(Ⅱ) helical coordination polymer {[Zn2(bpmphz)(Ac)2]·CH2OH·H2O}n (2), were synthesized and theirs crystal structures were determined by X-ray diffraction analysis. The ligand 1 crystalizes in orthorhombic, space group Pcca with a=2.016 3(1) nm, b=1.002 34(6) nm, c=1.995 86(8) nm, V=4.033 6(4) nm3, Z=8, Mr=405.42, Dc=1.335 g·cm-3, μ=0.095 mm-1, and features 1D layer structure. The complex 2 crystalizes in orthorhombic, space group P212121 with a=1.094 88(6) nm, b=1.173 12(6) nm, c=2.168 6(1) nm, V=2.785 5(3) nm3, Z=4, Mr=670.25, Dc=1.598 g·cm-3, μ=1.782 mm-1, and features 3D layer structure. They have been characterized by elemental analysis, IR, UV-Vis spectra and thermogravimetric and the fluorescence property of the compounds were investigated, which results showed that the compounds 1 and 1 exhibit luminescence with emission maximum at 470 and 510 nm at room temperature, respectively. |
