Abstract Five 2-azinyl-2H-benzotriazoles (azinyl = 2-pyridinyl, 2-pyrazinyl, 2-pyrimidinyl, 6-methoxy-3-pyridazinyl, 5-methyl-2-pyridinyl were prepared and characterized as bidentate ligands. The electronic structure of these and related heterocycles was investigated spectroscopically and computationally (TD-DFT). They were tested at the B3LYP/6-31++G(d, p)//B3LYP/6-31G(d, p) level of theory as ligands
摘要制备了5个2-氮杂基-2H-苯并三唑(氮杂基= 2-吡啶基,2-吡嗪基,2-嘧啶基,6-甲氧基-3-吡啶基,5-甲基-2-吡啶基),并作为二齿配体表征。这些和相关杂环的光谱和计算(TD-DFT)进行了研究,并在B3LYP / 6-31 ++ G(d,p)// B3LYP / 6-31G(d,p)的理论水平下进行了测试。 MgH2的配体,可以阐明络合物形成的趋势,其几何结构与环结构的关系以及氮原子在嗪环中的位置和位置Ru2 +带有2-吡啶基-2H的络合物7a-Ru制备了苯并三唑(7a)和两个bpy配体,并在结构,光谱和电化学方面进行了表征。 将结果与类似配合物的结果进行比较,并在MgH2配合物的计算结果的背景下进行讨论。
