中文摘要：

以2-苯胺基-4，6-二叔丁基苯酚（H2L）和FeCI2·4H2O为原料制备了一对手性半醌Fe（Ⅲ）络合物A-mer-[Fe（LlsQ）3]和△-mer-[Fe（LlsQ）3]（LlsQ：2-苯亚胺基-4，6-二叔丁基苯酚，mer：经式构型），通过单晶X射线衍射分析结合单晶压制片膜的固体圆二色（CD）光谱确定了该络合物的绝对构型，在此基础上建立了此类半醌络合物[M（LlsQ）3]（M=Cr，Fe，Co）的惟手性金属中心绝对构型与固体CD光谱之间的关联．此外，还对10份合成的[Fe（LlsQ）3]的大宗产物粉末与单晶的固体CD谱进行了比对分析，以及对1份合成产物进行10次重结晶的固体CD光谱表征．研究表明该化合物在结晶过程中发生了镜面对称性破缺（MSB），对映体过量（ee）值在15％-100％之间．

英文摘要：

A pair of chiral o-iminobenzosemiquinonato Fe（Ⅲ） complexes, A-mer-[Fe（LlSQ）3] and Zl-mer- [Fe（LlSQ）3] （LlSQ： 2-phenylimino-4,6-di-tert-butylphenol, mer： meridian configuration）, were synthesized from 2-anilino-4,6-di-tert-butylphenol （H2L） and FeCI2· 4H20. Their absolute configurations were determined by single crystal X-ray diffraction （XRD） and solid-state circular dichroism （CD） spectra （the same single crystal for XRD was dispersed in KCI）. Correlations between the absolute configurations of the chiral-at- metal o-iminobenzosemiquinonato M（III） complexes [M（LlSQ）3] （M=Cr, Fe, Co） and their solid-state CD spectra were also established. Comparison between solid-state CD spectra of the bulk samples from 10 different syntheses and their single crystals were thoroughly analyzed. The solid-state CD spectra of the powdered samples from 10 different crystallizations of one product were characterized. These studies indicated that mirror symmetry breaking （MSB） occurred during the crystallization process of the Fe（lll） complexes and their enantiomeric excess （ee） values were between 15% and 100%.
