hydrated copper(II) chloride or bromide with phenyl-2-picolyl ketone hydrazone and phenyl-2-picolyl ketone phenyl hydrazone, PPKhy and PPKPhy, respectively, have been studied employing elemental analyses, spectral studies (IR and electronic spectra) and the variable temperature magnetic susceptibility together with the electron spin resonance spectra. The complexes of the formulae [CuLX 2 ] 2 , L = PPKhy
摘要利用元素分析,光谱研究(IR和电子光谱)研究了水合氯化铜(II)或溴化物与苯基-2-吡啶甲基酮和苯基-2-吡啶甲基酮苯基,PPKhy和PPKPhy的相互作用)和可变温度磁化率以及电子自旋共振谱。发现式[CuLX 2] 2的配合物,L = PPKhy或PPKPhy,X = Cl或Br,是通过卤化物桥二聚的,而化学计量为[CuL 2] X 2的配合物本质上是单体。磁数据表明,二聚体配合物具有反铁磁相互作用。基于变温磁数据和ESR谱,讨论了磁相互作用的机理。
