[VO(acac)2] was used as a metal precursor to synthesize a series of mixed ligand oxidovanadium(IV) complexes [VIVO(L1–4)(LNN)] (1–5) with tridentate ONO donor arylazo ligands (H2L1–4) (where H2L1 = 1-(2-hydroxyphenyl)diazenyl)naphthane-2-ol, H2L2 = 1-(2-hydroxy-4-methylphenyl)diazenyl)naphthane-2-ol, H2L3 = 1-(2-hydroxy-4-nitrophenyl)diazenyl)naphthane-2-ol and H2L4 = 1-(2-hydroxy-4-bromophenyl)di
[VO(acac)2 ]用作金属前体与三齿ONO供体芳基偶氮合成一系列混合配体氧化钒(IV)络合物[V IV O(L 1-4)(L NN)](1-5)配体(H 2 L 1-4)(其中H 2 L 1 = 1-(2-羟基苯基)二氮烯基)萘-2-醇,H 2 L 2 = 1-(2-羟基-4-甲基苯基)二氮烯基)萘烷-2-ol,H 2 L 3 = 1-(2-羟基-4-硝基苯基)二氮烯基)萘-2-醇和H 2 L 4= 1-(2-羟基-4-溴苯基)二氮烯基)萘-2-醇)以及辅助配体(L NN),即2,2'-联吡啶(bipy)或1,10-菲咯啉(phen)共配体。所有配合物均通过光谱,ESI-MS和X射线晶体学技术表征,显示出扭曲的八面体几何形状。分子结构显示在六配位的V IV N 3 O 3几何形状中存在钒基。该物质表现出在-1.29和-1.37 V之间的准可逆单电子转移E c 1/2值,而不可逆的单电子氧化峰在0
