摘要:
由于单链磁体在信息储存设备、量子计算机及磁冰箱等方面的潜在应用，对该领域的研究仍然受到国内外科学家的重视.为了提高它的能垒以便能够付诸应用，需要选择适当的多齿螯合配体来构建相应的单链磁体配合物.首次选择多齿螯合配体水杨醛肟，并使之与叠氮钠、六水合氯化钴在甲醇溶液中反应得到一个结构新颖的铝纳混合金属一维链配合物，并对其进行单晶结构分析、红外光谱及元素分析表征.晶体结构研究表明该配合物中两个钴原子通过两个水杨醛肟上的肟基氧、氮原子及一个叠氮根离子的端基氮相连，再通过这两个水杨醛肟上的酚基氧原子和肟基氧原子与一个钠离子形成一个由2个钴和1个钠构成的结构单元，然后这些单元通过另一水杨醛肟上的肟基氧原子连接成一维链.此外，配合物中两个钴离子为+3价，所以该一维链是一个抗磁性链.
Abstract:
The investigation of single chain magnets was received a wide attention from the scientists at home and abroad because the potential application in high\|density information storage, quantum computing, magnetic refrigeration and so on. It is very important to choose appropriate chelate ligands to construct a proper 1D chain complex with single chain magnet properties to improve the energy barrier for practical application. A chelate ligand salicylaldehyde oxime was used, and it reacted with sodium azide and cobalt chloride hexahydrate in methanol, obtaining a novel cobalt\|sodium mixed metal 1D chain complex. Crystal structural studies indicate that in the complex, two cobalt atoms are linked by oxygen and nitrogen atoms from oximido groups of salicylaldehyde oximes and a terminal nitrogen atom from a azide ion. Then the above two cobalt ions are further linked to a sodium ion by a phenolic group oxygen and a oximido group oxygen of the above salicylaldehyde oxime ligands to form cobalt\|sodium units, which are connected to a 1D chain by a oximido group oxygen atom from another salicylaldehyde oxime ligand. Additionally, the valence states of the cobalt atoms in the complex are +3, so the complex is a diamagnetic chain.
