The synthesis of two diamagnetic dinuclear complexes [NiII2(LËË)2] (1) and [ZnII2(L)Cl4] (2) and an octahedral, paramagnetic, mononuclear complex [FeII(L)Cl2] (3) (S = 2) is reported; the tetradentate ligand N,Nâ²-bis(6-methyl-2-pyridylmethylene)ethane-1,2-diamine, L, is shown to be redox noninnocent. It exists in its neutral closed-shell form L in 2 and 3 and in its dianionic diradical form, (LËË)2â, in 1.
报道了两种抗磁性二核配合物[NiII2(L)2] (1)和[ZnII2(L)Cl4] (2)以及八面体顺磁性单核配合物[FeII(L)Cl2] (3) (S = 2)的合成;四齿
配体N,N-双(6-甲基-2-
