A new family of Fe(2)Ln complexes built from mononuclear anionic Schiff base subunits
Original language description
A series of the trinuclear [{Fe(3MeO-L)(2)}(2){u(6)-Ln(eta(2)-NO3)(H2O)}].nH(2)O, (Ln = Gd (2a), Tb (2b), Dy (2c), Ho (2d), Er (2e), Y (2f), H-2-3MeO-L = 2-hydroxy-3-methoxy-phenylsalicylaldimine) complexes were prepared and thoroughly characterized. Thecrystal structure of 2b was determined and it revealed that the heterotrinuclear complex consists of two anionic [Fe(3MeO-L)(2)](-) subunits coordinated to the [Tb(H2O)(eta(2)-NO3)](2+) bridging moiety through the phenolato and methoxy oxygen atoms. Theangular distortion within the coordination polyhedron of the [Fe(3MeO-L)(2)](-) subunits grows significantly upon coordination to the Ln atom of the bridging moiety, which consequently induces an increase in the parameter of the axial magnetic anisotropy. This conclusion is obvious from the comparison and analysis of the structural (XRD) and magnetic data of the yttrium trimer 2f and the precursor complex (Pr3NH)-[Fe(3MeO-L)(2)] (1, Pr3NH = the tripropylammonium cation), where D-Fe(1) =
