  • Heterodinuclear M<sup>II</sup>Ni<sup>II</sup>(M = Co, Ni, Cu, Zn) Complexes of a Macrocyclic Compartmental Ligand. Anomalous EPR of Cu<sup>II</sup>Ni<sup>II</sup>Complex by Coordination of 1-Methylimidazole
    作者:Ko-ji Inoue、Masaaki Ohba、Hisashi Okawa
    DOI:10.1246/bcsj.75.99
    日期:2002.1
    A phenol-based macrocyclic compartmental ligand, (L2;2)2-, having N(amine)2O2 and N(imine)2O2 metal binding sites sharing two phenolic oxygen atoms, has formed the following heterodinuclear MIINiII complexes: [CoNi(L2;2)(AcO)]PF6·CH3CN (1), [NiNi(L2;2)(AcO)]PF6 (2), [CuNi(L2;2)(AcO)]PF6 (3) and [ZnNi(L2;2)(AcO)]PF6·CH3CN (4). Furthermore, [CuNi(L2;2)(CH3CN)](PF6)2·CH3CN (3′) was obtained when 3 was recrystallized from acetonitrile. X-ray crystallographic studies for 1, 2, 3′ and 4 demonstrate that the MII resides in the N(amine)2O2 site and the NiII in the N(imine)2O2 site. The NiII in the N(imine)2O2 site has a planar geometry and is diamagnetic in all the complexes. The CoII of 1 and the NiII of 2 in the N(amine)2O2 site have a six-coordinate geometry together with a bidentate acetate group. The CuII in 3′ has a five-coordinate geometry together with one acetonitrile molecule, and the ZnII in 4 has a square-pyramidal geometry together with a unidentate acetate group. Complex 3′ in DMF combines 1-methylimidazole (MeIm) at the axial site of the NiII and the MeIm adduct in frozen DMF solution at 77.4 K shows EPR signals of g|| = 2.06 and g⊥ = 2.26 with a multi-line structure superimposed on the g|| component (A|| = 15.8 × 10-4 cm-1). The EPR signals are ascribed to the spin-doublet ground state (ST = 1/2) of antiferromagnetically coupled CuII(S = 1/2) - NiII(S = 1), and the multi-line structure is explained by considering hyperfine interaction with Cu nucleus (ACu = 50.0 × 10-4 cm-1) and superhyperfine interaction with N nucleus of MeIm (AN = 15.0 × 10-4 cm-1).
    一种基大环分隔配体,(L2;2)2-,具有共享两个氧原子的N(胺)2O2和N(亚胺)2O2属结合位点,已经形成了以下异双核MIINiII配合物:[CoNi(L2;2)(AcO)]PF6·CH3CN (1),[NiNi(L2;2)(AcO)]PF6 (2),[CuNi(L2;2)(AcO)]PF6 (3) 和 [ZnNi(L2;2)(AcO)]PF6·CH3CN (4)。此外,当3从乙腈中重结晶时,获得了[CuNi(L2;2)(CH3CN)](PF6)2·CH3CN (3′)。X射线晶体学研究1、2、3′和4表明,MII位于N(胺)2O2位点,而NiII位于N(亚胺)2O2位点。N(亚胺)2O2位点的NiII具有平面几何结构,并且在所有配合物中都是反磁性的。1中的CoII和2中的NiII在N(胺)2O2位点具有六配位几何结构,并与双齿乙酸盐基团结合。3′中的CuII具有五配位几何结构,并与一个乙腈分子结合,而4中的ZnII具有四角锥几何结构,并与单齿乙酸盐基团结合。在DMF中,3′配合物在NiII的轴向位点结合了1-甲基咪唑(MeIm),在77.4 K冷冻DMF溶液中,MeIm加合物显示了g|| = 2.06和g⊥ = 2.26的EPR信号,g||部分叠加了多线结构(A|| = 15.8 × 10-4 cm-1)。这些EPR信号归因于反磁耦合的CuII(S = 1/2) - NiII(S = 1)的自旋双重态基态(ST = 1/2),多线结构通过考虑与Cu核(ACu = 50.0 × 10-4 cm-1)的超精细相互作用和与MeIm的N核(AN = 15.0 × 10-4 cm-1)的超超精细相互作用来解释。

    D4d symmetry. Due to the disposition of the oxygen atoms around the Dy(III) ions, large easy-axis anisotropy is expected, which is responsible for the high thermal energy barriers for the reversal of the magnetization observed at zero field (in the 144–170 K range for all complexes). A preliminary correlation between the disposition of the oxygen atoms of the ligand (phenoxo and aldehyde) in the DyO8
