Reductive trapping of the cyclooctatetraenyl dianion (COT) by treatment of [Sm(DippForm)(thf)] (DippFormH = ,'-bis(2,6-diisopropylphenyl)formamidine; thf = tetrahydrofuran) with 1,3,5,7-cyclooctatetraene (CH) in toluene yields an inverse sandwich dinuclear complex [Sm(DippForm)(COT)] (1), but [Sm(DippForm)(COT)(thf)] (2) and [Sm(DippForm)(O-CH-DippForm)(thf)] (3) in thf, and 1 yields 2 and 3 on treatment with thf.
通过在甲苯中用1,3,5,7-环辛四烯（CH）处理[Sm(DippForm)(thf)]（DippFormH = ，'-双（2,6-二异丙基苯基）甲脒；thf = 四氢呋喃）对环辛四烯二价阴离子（COT）进行还原捕获，得到反夹心双核配合物[Sm(DippForm)(COT)]（1），但在四氢呋喃中得到[Sm(DippForm)(COT)(thf)]（2）和[Sm(DippForm)(O-CH-DippForm)(thf)]（3），并且1在用四氢呋喃处理时会生成2和3。
