摘要
本文合成了二种新的铜(Ⅱ)和铁(Ⅲ)配合物,Na_2[Cu(CHBen)(Py)_2]·H_2O和Na[Fe(CHBen)(Py)_2](CHBenH_4:N,N′-双-(3,5-二氯-2-羟基苯酰)-乙二胺;Py:吡啶)。经元素分析,红外,电子光谱,电导,磁矩及顺磁共振谱(ESR)等测定已推定二配合物中Cu(Ⅱ)和Fe(Ⅲ)的配位环境均为畸变八面体,Fe(Ⅲ)为高自旋态。文中指派了Na_2[Cu(CHBen)(Py)_2]·H_2O的d-d带归属,并对其ESR谱及有效磁矩进行了讨论。
Two novel complexes of Cu(Ⅱ) and Fe(Ⅲ), Na_2[Cu(CHBen)(Py)_2]·H_2O and Na[Fe(CHBen)(Py)_2] (CHBenH_4: 1,2-bis(3,5-dichloro-2-hydroxy-benzamido) ethane; py: pyridine), have been synthesized. Based on elemental analyses, IR, electronic spectra, conductivity, ESR and magnetic moment measurements, it can be concluded that the Cu(Ⅱ) ion and Fe(Ⅲ) ion in complexes exhibit both a distorted octahedron environmerit and Fe(Ⅲ) ion has a high spin state. The d-d band of Na_2[Cu(CHBen)(Py)_2]·H_2O has assigned and the ESR spectra are also discussed.
