Abstract

The reaction of zinc chloride with 2-benzylideneamino-5-methylphenol (LH), a bidentate Schiff base, in 1 : 1 molar ratio in the presence of triethylamine gives the ionic complex [Et₃NH]⁺[LZnCl₂]^– (I). The reaction between the zinc salt (chloride or acetate) and LH in 1 : 2 ratio results in complete displacement of the zinc salt anions to give bis-o-iminophenolate ZnL₂ (II), which exists in the crystalline state as the (ZnL₂)₂ dimer formed via μ-bridging oxygen atoms of two out of the four o-iminophenolate ligands. The molecular structure of ligand LH and complexes I and (II·CDCl₃)₂ was established by X-ray diffraction (CIF files CCDC nos. 2052647 (LH), 2052645 (I), 2052646 (II·CDCl₃)₂).

含双齿苯酚的 2-Benzylideneamino-5-Methylphenol Schiff 碱的单核和双核锌配合物

摘要

在三乙胺存在下，氯化锌与 2-亚苄基氨基-5-甲基苯酚 (LH)（一种二齿席夫碱）以 1:1 的摩尔比反应生成离子络合物 [Et ₃ NH] ⁺ [LZnCl ₂ ] ^– ( I）。锌盐（氯化物或醋酸盐）与 LH 以 1:2 的比例反应导致锌盐阴离子完全置换，生成双-邻亚氨基苯酚 ZnL ₂ ( II )，其以 (ZnL) 的结晶状态存在₂ ) _{2 个}二聚体通过 μ-桥接四个o-中两个的氧原子形成亚氨基苯酚配体。配体LH及其配合物I和( II ·CDCl ₃ ) ₂的分子结构通过X射线衍射确定(CIF文件CCDC nos. 2052647 (LH), 2052645 ( I ), 2052646 ( II ·CDCl ₃ ) ₂ )。
