Abstract The dicopper(II) complex, (NBu4)2[Cu2(L3-H)2] (1), with a new terdentate ONO-ligand (H3L3-H) containing amide nitrogen has been prepared. X-ray crystallographic analysis reveals that the complex has a di-μ-alkoxo-bridged dicopper(II) structure. Magnetic measurements for 1 indicate that a strong antiferromagnetic interaction is operative in the dicopper core with −2J value of 750 cm−1. Cyclic
摘要 制备了含有酰胺氮的新型三齿ONO-配体(H3L3-H) 的二铜(II) 配合物(NBu4)2[Cu2(L3-H)2] (1)。X 射线晶体学分析表明该配合物具有 di-μ-alkoxo-bridged dicopper(II) 结构。1 的磁性测量表明,强反铁磁相互作用在双铜芯中起作用,-2J 值为 750 cm-1。1 的循环伏安图在 +0.62 和 +0.88 V 处显示出不可逆的氧化波,这被指定为以金属为中心的氧化。
