Abstract The reaction of the unsymmetrical aliphatic tripodal ligand N[(CH 2 CH 2 NH 2 )(CH 2 CH 2 OH)(CH 2 CH 2 CH 2 OH)] (H 4 ‐3 ) with tris(acetylacetonato)iron(III) gives the dinuclear bis(μ‐alkoxo) bridged complex [Fe{N(CH 2 CH 2 N=C(CH 3 )CHC(CH 3 )O)‐ (CH 2 CH 2 CH 2 O)(CH 2 CH 2 O)}] 2 [Fe(η 5 , μ‐ 4 )] 2 ( 5 ). The new ligand 4 3‐ is obtained by reaction of the primary amine function of H 4 ‐3 with one of the acetylacetonato ligands under imine formation. The iron atoms in complex 5 are coordinated in an octahedral fashion within an N 2 O 4 environment. Complex 5 contains three different alkoxo donor groups.
