3,5-bis(2-hydroxyphenyl)-1-phenyl-1,2,4-triazole (H2L2, II) in methanol lead to the formation of the oxidovanadium(V) complexes [VVO(µ-L1)(OMe)]2 (1) and [VVO(µ-L2)(OMe)]2 (2). In the presence of KOH/CsOH, they give the corresponding dioxidovanadium(V) complexes. The isolated complexes K(H2O)[VVO2(L1)] (3), K(H2O)[VVO2(L2)] (4), Cs(H2O)[VVO2(L1)] (5), and Cs(H2O)[VVO2(L2)] (6) along with 1 and 2 have
[VIVO(acac)2] (acac = acetylacetonato) 与两个 ONO 三齿配体 4-[3,5-双(2-羟基苯基)-1,2,4-三唑-1-基]苯甲酸的反应( H2L1, I) 和 3,5-双(2-羟基苯基)-1-苯基-1,2,4-三唑 (H2L2, II) 在甲醇中形成氧化钒 (V) 络合物 [VVO(µ- L1)(OMe)]2 (1) 和 [VVO(µ-L2)(OMe)]2 (2)。在 KOH/CsOH 存在下,它们会生成相应的二氧化钒 (V) 配合物。分离的配合物 K(H2O)[VVO2(L1)] (3)、K(H2O)[VVO2(L2)] (4)、Cs(H2O)[VVO2(L1)] (5) 和 Cs(H2O) [VVO2(L2)] (6) 以及 1 和 2 已通过各种光谱技术(FTIR;UV/Vis;1H、13C 和 51V NMR)、元素分析、热研究、MALDI-TOF
