the absence of metal-metal interaction between vanadium atoms. Except the perchlorato complex, all other complexes behave like non-electrolytes in nitrobenzene. In the case of the perchlorate complex, the molar conductance value suggests the 1:2 electrolytic nature of the complex. Ir data indicate that ECAPO is bonded to the vanadium atom through oxygens of the carbonyl group and N -oxygen forming a seven-membered
摘要 2-乙氧基羰基氨基吡啶N-氧化物(ECAPO)的一些氧钒(IV)螯合物,其一般组成为VOX 2 ·ECAPO (X = Cl, Br, I, NO 3 , NCS or 0.5C 2 O 4 )和VO(C1O 4 ) 2 ·2ECAPO 已经通过化学分析、电导、摩尔质量、磁化率、红外和电子光谱被分离和表征。在室温 (30°C) 下测量的螯合物的磁化率表明钒原子之间不存在金属-金属相互作用。除高氯根配合物外,所有其他配合物在硝基苯中都表现得像非电解质。在高氯酸盐配合物的情况下,摩尔电导值表明配合物的 1:2 电解性质。Ir 数据表明 ECAPO 通过羰基的氧和 N-氧与钒原子键合,形成七元环。建议五配位氧钒 (IV) 化合物可以具有四方锥体结构。还讨论了螯合物的热性能。
