摘要

8-羟基-2-喹啉甲醛与3-溴苯胺缩合，再用NaBH4还原，得到了2-（（（3-溴苯基）氨基）甲基）喹啉-8-醇（HL）的新型三齿配体，并用NMR和质谱对其进行了表征。用醋酸锌或醋酸镉溶剂热法处理HL，得到双核配合物[Zn2(κ2-N,O-L)2μ-(κ2-N,O-L)2]·2ch40(1)和四核配合物[Cd4μ-(κ2-N,O-L)4μ-(κ3-N，N,O-L)2(κ2-O2CCH3)2](2)。通过单晶x射线衍射和粉末x射线衍射测定了配合物1和2的晶体结构，表明配体L−具有良好的连接性能和丰富的配位模式。并对配合物1、2进行了红外、核磁共振、紫外-可见光谱和质谱表征。

Synthesis, structures and properties of zinc and cadmium complexes with arylamine-modified 2-substituted 8‑hydroxyquinoline

Condensation of 8-hydroxy-2-quinolinecarbaldehyde and 3-bromoaniline, followed by reduction with NaBH₄, afforded a new potential tridentate ligand of 2-(((3-bromophenyl)amino)methyl)quinolin-8-ol (HL), which was characterized by NMR spectroscopies and mass spectrometry. Treatment of HL with zinc acetate or cadmium acetate using solvothermal method gave a dinuclear complex [Zn₂(κ²-N,O-L)₂μ-(κ²-N,O-L)₂]·2CH₄O (1) and a tetranuclear complex [Cd₄μ-(κ²-N,O-L)₄μ-(κ³-N,N,O-L)₂(κ²-O₂CCH₃)₂] (2), respectively. The crystal structures of complexes 1 and 2 were determined with single-crystal X-ray diffractions and powder X-ray diffractions, showing the good ligating property and rich coordination modes of the ligand L⁻. Moreover, the complexes 1, 2 were characterized by infrared, NMR, UV–vis spectroscopies and mass spectrometry.

期刊介绍： Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc. Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
