Ternary copper(II) complexes involving polypyridyl ligands in the coordination sphere of composition Cu(tpy)(phen)2 (1), Cu(tpy)(bipy)2 (2), Cu(tptz)(phen)2 (3) and Cu(tptz)(bipy)2 (4) where tpy = 2,2':6',2''-terpyridine, tptz = 2,4,6-tri(2-pyridyl)-1,3,5-triazine, phen = 1,10-phenanthroline and bipy = 2,2'-bipyridine have been synthesized and characterized by elemental analysis, magnetic susceptibility, X-band e.p.r. spectroscopy and electronic spectroscopy. Single crystal X-ray of (1) has revealed the presence of a distorted square pyramidal geometry in the complex. Magnetic susceptibility measurements at room temperature were in the range of 1.77-1.81 BM. SOD and antimicrobial activities of these complexes were also measured. Crystal data of (1): P-1, a = 9.3010(7) A, b = 9.7900(6) A, c = 16.4620(6) A, Vc = 1342.73(14) A3, Z = 4. The bond distance of CuN in square base is 2+/-0.04 A.
已合成了组成分别为Cu(tpy)(phen)2 (1)、Cu(tpy)(bipy)2 (2)、Cu(tptz)(phen)2 (3)和Cu(tptz)(bipy)2 (4)的三元铜(II)配合物，其中tpy = 2,2':6',2''-三联吡啶，tptz = 2,4,6-三(2-吡啶基)-1,3,5-三嗪，phen = 1,10-菲咯啉，bipy = 2,2'-联吡啶，并通过元素分析、磁化率、X波段电子顺磁共振光谱和电子光谱对其进行了表征。(1)的单晶X射线分析表明该配合物中存在扭曲的四方锥几何构型。室温下的磁化率测量值在1.77 - 1.81玻尔磁子范围内。还测定了这些配合物的超氧化物歧化酶和抗菌活性。(1)的晶体数据：P-1，a = 9.3010(7) Å，b = 9.7900(6) Å，c = 16.4620(6) Å，Vc = 1342.73(14) Å3，Z = 4。方形基底中CuN的键长为2±0.04 Å。
