通过水热方法,用2,4,4′-联苯三羧酸(H3btc)和菲咯啉(phen)分别与Mn Cl2·4H2O和Ni Cl2·6H2O反应,合成了2个具有双核结构的配合物[Mn2(Hbtc)2(phen)4]·5H2O(1)和[Ni2(Hbtc)2(phen)4]·2H3btc·4H2O(2),并对其结构和磁性质进行了研究。结构分析结果表明2个配合物的晶体都属于三斜晶系,P1空间群。配合物1和2均为双核结构,通过分子间的O-H…O氢键作用,双核的分子被进一步连接成了三维超分子框架。研究表明,双核分子中相邻金属离子间存在反铁磁相互作用。
By hydrothermal method, 2,4,4’-biphenyl tricarboxylic acid (H3btc) and phenanthroline (phen) were respectively reacted with Mn Cl2 4H2O and Ni Cl2 6H2O to synthesize two complexes with binuclear structure [Mn2 (Hbtc) 2 (phen) 4] · 5H2O (1) and [Ni2 (Hbtc) 2 (phen) 4] · 2H3btc · 4H2O (2) were synthesized and their structures and magnetic properties were studied. The structural analysis results show that the crystals of the two complexes all belong to the triclinic and P1 space group. Both complexes 1 and 2 are binuclear structures. Through the O-H ... O hydrogen bonding between molecules, the binuclear molecules are further linked into a three-dimensional supramolecular framework. Studies have shown that there is antiferromagnetic interaction between adjacent metal ions in the binuclear molecule.
