A new fused ring compound, 2,6-dibutyl-4,8-dimethyl-1,5-dihydro-s-indacene (VII) (H2L), has been synthesized from 2,5-dimethyl-1,4-dibromomethylbenzene in almost quantitative yield. Two organomtallic binuclear complexes, [Cp*Fe-L-FeCp*] (1) and the mixed-valence compound [Cp*Fe-L-FeCp*]+ BF–4 (2), have been characterized by spectroscopic and electrochemical techniques. The cyclic voltammogram of 1 exhibits a potential difference of 668 mV between two redox peaks and the UV-vis-NIR spectra of compound 2 shows an intervalance charge transfer band at 1794 nm. The information gathered by these techniques indicates that the studied binuclear complex has strong interaction between the two metal centres.
一种新的融合环化合物2,6-二丁基-4,8-二甲基-1,5-二氢-茚烯(VII)(H2L)已经从2,5-二甲基-1,4-二溴甲基苯合成,收率几乎定量。两种有机金属双核配合物,[Cp*Fe-L-FeCp*](1)和混合价态化合物[Cp*Fe-L-FeCp*]+BF4-(2),已经通过光谱和电化学技术进行表征。1的循环伏安图表现出两个氧化还原峰之间的电位差为668毫伏,化合物2的UV-vis-NIR光谱显示出一个间隔价电子转移带在1794纳米处。这些技术收集的信息表明,研究的双核配合物之间存在着强烈的金属中心之间的相互作用。
