maleonitrile-tethered ligand. Whereas, Co(II) interacted differently with each member of HL1-Ar. With the presence of an electron-donating group (EDG), a methyl group (at ortho and para positions) in the phenyl ring of HL1-Mes, Co(II) could selectively perform the ligand transformation. On the other hand, HL1-CF3 and HL1-OMe (with the presence of less EDG in the phenyl ring in comparison to HL1-Mes) did
两组马来腈系链的 N 原子供体三齿配体,其构型异构,2-(( E )-(芳基-亚甲基)氨基)-3-((吡啶-2-基甲基)氨基)马来腈 ( HL 1 -Ar ) 和 2-((aryl-methyl)amino)-3-(( E )-(pyridin-2-ylmethylene)amino)maleonitrile ( HL 2-Ar ) 已被合成并充分表征(其中芳基是4-甲氧基苯基 ( HL 1-OMe / HL 2-OMe )、4-(三氟甲基)苯基 ( HL 1-CF3 / HL 2-CF3 ) 和 2,4,6-三甲基苯基 ( HL 1-Mes / HL 2-Mes)). 探讨了配体的电子效应和金属离子类型对 Co( II ) 和 Ni( II ) 金属离子与不同电子调谐配体的反应性的竞争作用。发现Ni( II ) 金属离子对HL 1-Ar到HL 2-Ar (对于芳基上的所有取代)的不可逆转
