Copper(II) and H+ complexes of 3,3,8,8-tetramethyl-4,7-diazadecane-2,9-dione dioxime, 3,3,9,9-tetramethyl-4,8-diazaundecane-2,10-dione dioxime and 3,3,10,10-tetramethyl-4,9-diazadodecane-2,11-dione dioxime have been studied at 25 °C and ionic strength 0.15 mol dm–3 NaCl, using glass-electrode potentiometry. Electronic spectra have been used to postulate structures for the different species in solution. In each case the metal binds to the four nitrogen atoms of the oxime. In the MLH–1 species hydrogen bonding between the terminal oxime groups produces a pseudo-macrocycle. Computer simulation has been used to predict the effect of the ligands on the blood-plasma metal-ion distribution in vivo.
在 25 °C、离子强度为 0.15 mol dm-3 NaCl 的条件下,使用玻璃电极电位计研究了 3,3,8,8- 四甲基-4,7-二氮杂十烷-2,9-二酮二氧肟、3,3,9,9-四甲基-4,8-二氮杂十一烷-2,10-二酮二氧肟和 3,3,10,10- 四甲基-4,9-二氮杂十二烷-2,11-二酮二氧肟的铜(II)和 H+ 复合物。电子光谱被用来推测溶液中不同物种的结构。在每种情况下,金属都与肟的四个氮原子结合。在 MLH-1 物种中,末端肟基之间的氢键产生了一个伪大循环。计算机模拟被用来预测配体对体内血浆金属离子分布的影响。
