Synthesis, structural characterization, and spectroscopic and magnetic properties of three new cyano-bridged 3d-4f bimetallic complexes, Ln III(DMF)4(H2O)3CrIII (CN)6·nH2O (Ln = Nd, Sm, Gd), have been described. The Nd-Cr complex crystallizes in the monoclinic P21/n space group with the following unit cell parameters: a = 20.063(7) Å, b = 8.967(4) Å, c = 18.023(6) Å, b = 96.12(3)°, V = 3224(2) Å3, and Z = 4. The neodymium (III) ion, which adopts anti-prism eight-coordination environment, is linked to the [CrIII(CN) 6]3- moiety through a bridging cyanide ligand with Nd-N = 2.550(4) Å and Nd-N-C = 164.4(4)°. The variable-temperature (0.5 T at 2-300 K) and variable-field (0-5 T at 2 and 5 K) magnetic measurements reveal that the weak interaction of Gd-Cr complexes differs from that of Nd-Cr and Sm-Cr ones mainly because of the lack of orbital angular momentum. The XPS and diffuse reflectance electronic spectra were also measured to discuss charge transfer transitions concerning π-backdonation from the viewpoint of magneto-optical functions.
