Ni-N (amine) distances [l]. On the other hand, the effects mentioned above may increase the acidity of the amidic hydrogen so that the amides could become anions in basic solution; the latter are good udonors. Thus high-valent metal complexes are expected to be formed with multiamido ligands.
罐头(Tscyclam)已被用来降低cyclam的配位能力; [Ni(Tscyclam)(
H2O2)2] CIZ的晶体结构表明,Ni-N(酰胺)距离比Ni-N(胺)距离长0.3A。另一方面,上述效果可能会增加酰胺氢的酸度,使酰胺在碱性溶液中成为阴离子。后者是好人。因此,期望与多酰胺
配体形成高价
金属络合物。
