摘要
采用谱学和X射线单晶衍射技术,分别对四苯基铁杂环戊二烯羰基铁配合物（μ_2,η~4-C_4Ph_4）Fe_2（CO）_6（1）和四苯基取代环戊二烯酮（Ph_4C_4CO）（2）的晶体结构进行了分析和表征。在太阳光和氙灯光（带有4种滤光片）的照射下,利用红外吸收光谱,详细地考察了配合物1的光分解过程和分解产物。实验结果表明,配合物1的光分解速率与光源和波长有关,太阳光的光解速率最快;在同一氙灯光源下,全波长滤光片（320~780 nm）的光解速率最快。本文还对配合物1的热分解和溴分解反应进行了对比研究,结果证实,3种分解反应的主要产物均为配体2。
The crystal structures of hexa-carbonyl-di-iron complex with ferratetraphenyl cyclopentadiene ring（μ_2,η~4-C_4Ph_4）Fe_2（CO）_6（1） and tetraphenyl substituted cyclopentadienone ligand（Ph_4C_4CO）（2） were characterized by spectroscopic determination and X-ray single crystal diffraction technique. The decomposition products and process of ferrole complex 1 were studied by FTIR, using sun light and xenon lamp with four filters as light source, respectively. The results show the light decomposition rate of ferrole complex 1 relates to light source and wavelength. The decomposition rate of sun light source is the fastest, and the decomposition rate of whole wavelength（320~780 nm） is correspondingly faster than that of other wavelengths under irradiation of the same xenon lamp. Ligand 2 is the main product from three decomposition reactions of ferrole complex 1 in the presence of light, heat and Br_2 in acetic acid, respectively. CCDC：937369, 1; 937370, 2.
