合成了一维配位聚合物{[Cu(tzda)(H2O)3].3.5H2O}n(H2tzda为1,3,4-噻二唑-2,5-二硫代乙酸),对其结构进行了红外、元素分析和X射线单晶衍射测定.配合物属单斜晶系,空间群C2/c,晶胞参数a=1.907 3(12)nm,b=0.713 4(4)nm,c=2.363 5(15)nm,β=91.378 0(10)°,Z=8.金属中心Cu(Ⅱ)离子呈现出五配位,处于四角锥的配位环境;配体阴离子tzda2-采用双(单)齿配位模式将Cu(Ⅱ)离子连接成一维链状结构.配合物的电化学研究表明:在-0.3~0.4 V电位范围内,Cu2+/Cu+电对在电极上的氧化还原反应过程是准可逆过程且受扩散控制.
A one-dimensional coordination polymer {[Cu (tzda) (H2O) 3] 3.5H2O} n (H2tzda is 1,3,4-thiadiazole-2,5-dithioacetic acid) The complex was monoclinic with space group C2 / c, cell parameters a = 1.907 3 (12) nm, b = 0.713 4 (4) nm, c = 2.363 5 (15) nm, β = 91.378 0 (10) °, Z = 8. Cu (Ⅱ) ions in the center of the metal exhibit a five-coordinate and are located in the coordination environment of the quadrangular pyramid. The ligand anions tzda2- Single) tooth coordination mode, the Cu (Ⅱ) ions are connected into one-dimensional chain structure.The electrochemical studies of the complexes show that the redox reaction of Cu2 + / Cu + on the electrode in the potential range of -0.3 ~ 0.4 V Quasi-reversible process and controlled by diffusion.
