Mixed-metal chain complexes constructed from lantern-type dinuclear ruthenium(II,III) carboxylate unit and tetracyanidonickelate(II), (PPh4)n[Ru2(O2CCH3)4Ni(CN)4]n·nH2O (1) and(PPh4)n[Ru2{O2CC(CH3)3}4]3n[Ni(CN)4]2n·2nH2O (2), were synthesized and characterized by elemental analysis, IR, and UV-vis spectroscopies. These data are in accordance with the formation of the chain complex with an alternative arrangement of the dinuclear Ru2 unit and tetracyanidonickelate(II). A broad band at near-IR and a band at visible region (1058 and 452 nm for 1 and 1082 and 454 nm for 2) were observed in the diffused refl ectance spectra and ascribed to a δ(Ru2)→δ*(Ru2) and a π(RuO, Ru2)→π*(Ru2) transitions, respectively. Temperature-dependence of magnetic susceptibility (4.5—300 K) showed that the antiferromagnetic interaction between the dinuclear units is weak (zJ = −0.2 cm−1) with D value of 75 cm−1 for both complexes. |
