六氟磷酸盐 [Fe(C5H4tBu)2]PF6 (1) 和 [Co(C5 H4 tBu)2]PF6 (2) 以具有中心对称阳离子的同型结构结晶，这些阳离子具有完全平行的环配体的交错（反式）构象（构象角 τ = 180°）。四氯钴酸盐，[Co(C5H4tBu)2 ]2 CoCl4 (3)，含有一个几乎重叠 (τ = 140.4°) 和一个几乎交错 (τ = 101.4°) 的钴茂正离子；在这两种情况下，环戊二烯基环平面都略微倾斜（分别为 α = 5.4° 和 4.1°），为叔丁基取代基提供更多空间，在所有三种配合物 1 - 3 中，叔丁基取代基远离金属弯曲
The hexafluorophosphate salts [Fe(C5H4tBu)2]PF6 (1) and [Co(C5 H4 tBu)2]PF6 (2) crystallize in isotypic structures with centrosymmetric cations which have a staggered (transoid) conformation of the exactly parallel ring ligands (conformational angle τ = 180°). The tetrachlorocobaltate salt, [Co(C5H4tBu)2 ]2 CoCl4 (3), contains one almost eclipsed (τ = 140.4°) and one almost staggered (τ = 101.4°) cobaltocenium cation; in both cases, the cyclopentadienyl ring planes are slightly inclined (by α = 5.4° and 4.1°, respectively) to give more room to the tert-butyl substituents which are bent away from the metal in all three complexes 1 - 3
