Three new heterometallic 1D coordination polymers [FeIII2Pr(4-Me-sal)4(2,2′-bipy)2(H2O)6](NO3) · 2MeOH · 1.5H2O (1), [FeIII2Gd(4-Me-sal)4(2,2′-bipy)2(H2O)5]Cl1/2(NO3)1/2 · 5H2O (2) and [FeIII2Dy(4-Me-sal)4(2,2′-bipy)2(H2O)5]Cl1/2(NO3)1/2 · 5H2O (3) have been synthesized. 1 and 2 were characterized by single-crystal X-ray crystallography, and 3 was shown to be isomorphous to 2 by X-ray powder diffraction. Magnetic studies show that the three compounds show a similar temperature dependence of their magnetic susceptibilities over the range 1.8–300 K. The observed decrease of χT with decreasing temperature for all three compounds could be the result of antiferromagnetic interactions between Fe–Ln centres and/or the depopulation of the Stark sublevels in the case of the anisotropic Ln ions (PrIII and DyIII).
