Abstract

The reaction of Ln(NO₃)₃·aq with K ₃[Fe(CN)₆] or K₃[Co(CN)₆] and 2,2′-bipyridine in water led to five one-dimensional complexes: trans-[M(CN)₄(μ-CN)₂Ln(H₂O)₄ (bpy)]_n·XnH₂O·1.5nbpy (M = Fe³⁺ or Co³⁺; Ln = Sm³⁺, Gd³⁺, or Yb³⁺; X = 4 or 5). The structures for [Fe³⁺-Sm³⁺] (1), [Fe ³⁺-Gd³⁺] (2), [Fe³⁺-Yb³⁺] (3), [Co³⁺-Gd³⁺] (4), and [Co³⁺-Yb³⁺] (5) have been solved; they crystallize in the triclinic space P1 and are isomorphous. The [Fe³⁺-Sm³⁺] complex is a ferrimagnet, its magnetic studies suggesting the onset of weak ferromagnetic 3-D ordering at 3.5 K. The [Fe³⁺-Gd³⁺] interaction is weakly antiferromagnetic. The isotropic nature of Gd³⁺ allowed us to evaluate the exchange interaction (J = 0.77 cm^-1).
