Abstract

An efficient synthesis of a new class of “Dipodal s-triazine Schiff base ligand” has been developed based on high-yielding amines substitutions of 2-vinyl-4,6-diamino-1,3,5-triazine (acryloguanamine) (VDAT) by salicylaldehyde. A new compound characterized by a dipodal s-triazine pentadentate Schiff base with 2-vinyl-4,6-N,N’-bis(2,4-dihydroxybenzylidine)-1,3,5-triazine [VDAT24] has been developed. The obtained [VDAT24] was polymerized to obtain poly(2-vinyl-4,6-N,N’-bis(2,4-dihydroxybenzylidine)-1,3,5-triazine) [PVDAT24]. Subsequently, s-Triazine-centered Fe(III) homonuclear complexes [VDAT24Fe], and polynuclear complexes [PVDAT24Fe] were obtained derived. As a result, the ligand obtained by elemental analysis, ICP-AES, TGA, FTIR, ¹H NMR and ¹³C NMR. Isolated ligand complex, FTIR, TGA, and were illuminated structures on the magnetic susceptibility. The resulting two different polymeric ligands and certain complexes of FTIR, TGA, and Ostwald Viscometer elucidated the structures of magnetic susceptibility.

五正齿二极 s-三嗪希夫碱配体的 FeIII 同核和多核配合物研究

基于水杨醛对 2-乙烯基-4,6-二氨基-1,3,5-三嗪（丙烯酰胍胺）（VDAT）的高产胺取代，开发了一种新型 "二极 s-三嗪希夫碱配体 "的高效合成方法。我们开发出了一种新化合物，其特征是 2-乙烯基-4,6-N,N'-双（2,4-二羟基苄基啶）-1,3,5-三嗪与 2-乙烯基-4,6-N,N'-双（2,4-二羟基苄基啶）-1,3,5-三嗪形成了二极 s-三嗪五价席夫碱[VDAT24]。将得到的[VDAT24]进行聚合，得到聚(2-乙烯基-4,6-N,N'-双(2,4-二羟基苄基)-1,3,5-三嗪)[PVDAT24]。随后，又衍生出了以 s-三嗪为中心的铁(III)同核配合物[VDAT24Fe]和多核配合物[PVDAT24Fe]。因此，通过元素分析、ICP-AES、TGA、傅立叶变换红外光谱、1H NMR 和 13C NMR 获得了配体。分离出的配体复合物、傅立叶变换红外光谱（FTIR）、热重分析仪（TGA）和磁感应强度都显示了其结构。由此产生的两种不同的聚合物配体和某些络合物的傅立叶变换红外光谱、热重分析和奥斯特瓦尔德粘度计阐明了磁感应强度的结构。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
