title = "Structural, magnetic, and 1H NMR spectral study on lantern-type cis-and trans-diruthenium(II,III) complexes with two formamidinato and two acetato bridges",
abstract = "Lantern-type dinuclear complexes, cis-[Ru2(4-Me-pf) 2(O2CMe)2Cl] and trans-[Ru2(2,6- Et2-pf)2(O2CMe)2Cl] (4-Me-pf - = N,N′-bis(4-methylphenyl)formamidinate ion and 2,6-Et 2-pf- = N,N′-bis(2,6-diethylphenyl)formamidinate ion), were prepared and characterized. The dinuclear structures with cis-and trans-arrangements of the bridging ligands were confirmed by the X-ray crystal structures as well as 1H NMR spectra (298 K) in CD2Cl 2, where the proton signals were observed at widely spread positions δ = -80 to 25 ppm. Variable-temperature magnetic moments (2-300 K) showed the existence of three unpaired electrons in dinuclear units with large D values (65 cm-1 for cis-Ru2II,III and 90 cm -1 for trans-Ru2II,III).",
