4-triazole)] with aquated Cu(CF3SO3)2, Cu(NO3)2, and Cu(ClO4)2, respectively, in water results in the trinuclear complexes [Cu3(OH)(aat)3(CF3SO3)(H2O)2](CF3SO3) (1), [Cu3(OH)(aat)3(NO3)(H2O)2](NO3).(H2O)2 (2), and [Cu3(OH)(aat)3(ClO4)(H2O)2](ClO4) (3). The synthesis, X-ray structure, and magnetic and spectroscopic properties of the three title complexes are described. The cation of the three complexes is trinuclear
Haat [Haat =(3-乙酰氨基-1,2,4-三唑)]与水中的Cu(CF3SO3)2,Cu(NO3)2和Cu(ClO4)2的反应分别在水中产生三核配合物[Cu3(OH)(aat)3(CF3SO3)(H2O)2](CF3SO3)(1),[Cu3(OH)(aat)3(NO3)(H2O)2](NO3)。(H2O)2 (2)和[Cu3(OH)(aat)3(ClO4)(H2O)2](ClO4)(3)。描述了三种标题配合物的合成,X射线结构以及磁和光谱性质。这三个配合物的阳离子是三核的,带有一个Cu3OH骨架,该骨架具有三唑环的NN二嗪基团作为每对铜原子之间的桥。Cu3OH单元的平均Cu-O距离为1.991(6)(1),2.000(6)(2)和2.007(6)(3)A,平均Cu-Cu'距离为3.355(2)( 1),3.341(1)(2)和3.371(3)(3)A,平均Cu-O-Cu'角为114
