吡啶-2,6-二羧酸桥联的双核钴配合物的磁性

Magnetic properties of a pyridine-2,6-dicarboxylate bridged dinuclear cobalt(Ⅱ) complex

吡啶-2,6-二羧酸与硝酸钴在水热条件下反应得到双核配合物[Co2(pdc)2(H2O)5].2H2O.磁性研究表明在该配合物中钴离子间存在反铁磁交换耦合相互作用.

One dinuclear complex, [Co2（pde）2（H2O）5 ] .2H2O, was synthesized by reaction of pyridine-2,6-dicar- boxylic acid （pdcH2） with Co（NO3）2.6H2O under hydrothermal condition. Magnetic susceptibility measurements indicated that 1 shows antiferromagnetic exchange interaction between the Co（ Ⅱ ） ions.
