用取代乙二胺与水杨醛缩合得到钴（II）与希夫碱配合物，并与五配位吡啶加合物合成。esr，电子，和cd光谱和磁化率已被报道。为了拟合磁性，并允许对观察到的吸收带进行分配，用配体场方法计算了能级格式。从钴原子的电子排布和取代基对取代的乙二胺的碳原子的空间效应两方面研究和讨论了与氧的反应。
Complexes of cobalt(II) with Schiff bases obtained by condensation of salicylaldehyde with substituted ethylenediamines have been synthesised together with five-co-ordinated pyridine adducts. E.s.r., electronic, and c.d. spectra and magnetic susceptibilities have been reported. Energy level schemes have been calculated by a ligand field approach in order to fit the magnetic properties and allow an assignment of the observed absorption bands. The reaction with oxygen has been studied and discussed in terms of both the electron configuration of the cobalt atom and the steric effects of substituents on the carbon atoms of the substituted ethylenediamines.
