摘要
A new 1D copper（Ⅱ） polymer [Cu（Hpt）（3,5-DMBA）]n has been hydrothermally synthesized with copper acetate,3-（pyridin-2-yl）-1,2,4-triazole（Hpt） and 3,5-dimethylbenzoic acid（3,5-DMBA）. It crystallizes in triclinic space group P1,with a = 8.1974（6）,b = 8.3280（6）,c = 12.5021（9） ？,α = 84.3320（10）,β = 71.8870（10）,γ= 65.4560（10）o,V = 737.44（9） ？~3,Dc = 1.612 g/cm3,Z = 2,F（000） = 366,GOOF = 1.035,R = 0.0298 and w R = 0.0855. The crystal structure is a one-dimensional（1-D） chain in which the Cu（Ⅱ） is five-coordinated with square pyramidal geometry. The crystal structure shows that the whole molecule consists of two copper ions bridged by two μ12-η：η0-3,5-dimethylbenzoic acid anions and two 3-（pyridin-2-yl）-1,2,4-triazole molecules. The coordination environment of Cu（Ⅱ） ion is CuO＋2N_3. The luminescence and thermal properties of the complex were investigated.
