已经制备了一系列环戊二烯基（芳烃）铁（II）夹层络合物、结构相关的二茂铁和（四甲基环丁二烯）钴与α-、β-或γ-环糊精（α-、β-、γ-cd）的包合物。 具有空间要求的环配体的配合物被选择性地包含在β-或γ-cd中。 对七种新型 α-CD 加合物的 X 射线晶体学研究表明，通道型结构中 α-CD 大环化合物的分子堆积取决于客体配合物的尺寸和形状。 两种β-cd加合物的晶体结构测定揭示了与相应的α-cd加合物相似的通道型结构，尽管在这些情况下，由于无序而无法确定客体分子的确切方向。
Inclusion compounds of a range of cyclopentadienyl(arene)iron(II) sandwich complexes, structurally related ferrocenes and (tetramethylcyclobutadiene)cobalt complexes with alpha-, beta- or gamma-cyclodextrin (alpha-, beta-, gamma-cd) have been prepared. Complexes bearing sterically demanding ring ligands were selectively included in beta- or gamma-cd. X-Ray crystallographic studies of seven new alpha-cd adducts demonstrate that the molecular packing of the alpha-cd macrocycles in channel-type structures depends on the size and shape of the guest complexes. Crystal structure determinations of two of the beta-cd adducts reveal a channel-type structure similar to that of the corresponding alpha-cd adducts, although in these cases the exact orientation of the guest molecules could not be determined due to disorder.
