Trinuclear Ni^II-Ln^III-Ni^II Complexes with Schiff Base Ligands: Synthesis, Structure, and Magnetic Properties.

ABSTRACT: The reaction of the Schiff base ligand o-OH-C₆H₄-CH=N-C(CH₂OH)₃, H₄L, with Ni(O₂CMe)₂∙4H₂O and lanthanide nitrate salts in a 4 : 2 : 1 ratio lead to the formation of the trinuclear complexes [Ni₂Ln(H₃L)₄(O₂CMe)₂](NO₃) (Ln = Sm (1), Eu (2), Gd (3), Tb (4)). The complex cations contain the strictly linear Ni^II-Ln^III-Ni^II moiety. The central Ln^III ion is bridged to each of the terminal Ni^II ions through two deprotonated phenolato groups from two different ligands. Each terminal Ni^II ion is bound to two ligands in distorted octahedral N_2<
