| Abstract: Ahydrazone Schiff base monohydrate, C17H20N4O2·H2O (1), was synthesized by rection of 4-diethylamino -salicylaldehyde and isoniazide, and its zinc(Ⅱ) coordination polymer, [Zn(L)(Phen)]∞ (2) with double helix structure, was prepared. They have been characterized by elemental analysis, IR, UV-vis spectra and X-ray diffraction single crystal analysis and the fluorescence property of the compounds were investigated, which result showed that the crystal of 1 belongs to the triclinic system,space group P1 with cell parameters a=0.71058(4) nm, b=1.0045(2) nm, c=1.3054(3) nm, α=97.383(11)°, β=102.989(12)°, γ=104.038(10)°, V=8.641(3) nm3, Z=2, Mr=330.39, Dc=1.270 g·cm-3 and the crystal of 2 belongs to the trigonal system,space group P32 with cell parameters a=1.68654(12) nm, b=1.68654(12) nm, c=0.79656(12) nm, V=1.9622(5) nm3, Z=3, Mr=555.93, Dc=1.411 g·cm-3. The compounds 1 and 2 exhibit luminescence with emission maximum at 524 and 535 nm at room temperature, respectively. CCDC: 995121, 1; 994066, 2. |
