A molecular carousel , that is the appearance of the structure of the title compound [ 1 ⋅2 py] (see picture), the first complex of a new structure type prepared by a highly selective condensation reaction from the equally new complex [Fe(C 5 H 4 GaMe 2 ) 2 ]. The first gallium bridged [ m.m ]ferrocenophane [{Fe(C 5 H 4 ) 2 } 2 {GaMe(C 5 H 5 N)} 2 ] is formed as an intermediate; this compound can also be prepared in a planned synthesis and can be converted into [ 1 ⋅2 py] by warming. The complex [ 1 ⋅2 py] as well as [ 1 ⋅2 Et 2 O] and [ 1 ⋅2 DMSO], which were formed by donor exchange, offers various interesting properties, for example, [ 1 ⋅2 DMSO] can be reversibly oxidized to the mono‐, di‐, and trication.
