The sterically demanding pentaarylcyclopentadienyl radical Cp^BIGt-Bu• (1; Cp^BIGt-Bu = Cp(4-t-Bu-Ph)₅) reacts with group 2, group 13, and group 14 metal amalgams to form the following complexes of the type Cp^BIGt-Bu₂M (M = Ca (3), Sr (4), Ba (5)), Cp^BIGt-BuM′ (M′ = Ga (6), In (7), Tl (8)) and Cp^BIGt-Bu₂M′′ (M′′ = Sn (10), Pb (11)). In addition, metallocenes Cp^BIG₂Mg (2), Cp^BIG₂Hg (12), and Cp^BIG₂Ge (9) were formed in reactions of 1 with magnesium anthracene (2) and elemental mercury (12) as well as by salt metathesis between Cp^BIGt-BuK and GeCl₂·dioxane (9). 6 was found to react with (coe)Cr(CO)₅ (coe = cis-cyclooctene) with formation of Cp^BIGt-BuGaCr(CO)₅ (13). 2–13 were characterized by elemental analysis and IR and NMR spectroscopy. In addition, the solid-state structures of 2, 4, 5, and 9–13 were determined by single-crystal X-ray diffraction.

s，p和d嵌段金属的五芳基环戊二烯基三明治和半三明治络合物的直接合成

具有空间要求的五芳基环戊二烯基Cp ^{BIG t} -Bu ^•（1； Cp ^{BIG t -Bu} = Cp（4- t -Bu-Ph）₅）与第2组，第13组和第14组金属汞齐反应形成以下配合物类型Cp ^{BIG t -Bu}₂ M（M = Ca（3），Sr（4），Ba（5）），Cp ^{BIG t -Bu} M'（M'= Ga（6），In（7）， Tl（8））和Cp ^{BIG t -Bu}₂ M''（M''= Sn（10），Pb（11））。此外，茂金属Cp ^BIG₂ Mg（2），Cp ^BIG₂ Hg（12）和Cp ^BIG₂ Ge（9）在1与蒽镁（2）和元素汞（12）的反应中形成，并通过Cp ^{BIG t -Bu} K与GeCl ₂ ·二恶烷之间的盐复分解反应（9）。发现6与（coe）Cr（CO）₅（coe =顺式-环辛烯）反应形成Cp ^BIG吨-Bu GaCr（CO）₅（ 13）。2 – 13通过元素分析，IR和NMR光谱进行了表征。此外，固态结构2， 4， 5，和9 - 13通过单晶X射线衍射来确定。
