Great bowls of fire: The rotation of the cyclopentadienyl (Cp) ring is restricted in two concave-bound monoalkyl-substituted CpFe(eta(6)-sumanene) "pi-bowl" complexes (see picture). The asymmetric stacking of atropisomers was observed with a MeCpFe complex in the solid state and the chiral (S)-sBuCpFe complex showed magnetic and optical desymmetrization of the sumanene ligand, which is the first example of a chiral complex of a pi-bowl ligand.
大碗状火焰
在两个凹面结合的单烷基取代的[CpFe(η(6)-苝烯)]⁺“π碗”配合物中，环戊二烯基（Cp）环的旋转受到限制（见图）。在固态下，用甲基环戊二烯基铁配合物观察到阻转异构体的不对称堆积，手性（S）-仲丁基环戊二烯基铁配合物显示出苝烯配体的磁去对称化和光学去对称化，这是π碗配体手性配合物的首个实例。
