摘要：
The syntheses, crystal structures and electronic absorption spectra of cyanide-bridged complexes trans-Ru-II(dppe)(2)(CN)(2)((FeX3)-X-III)(2) (X = Cl, 2; X = Br, 3; dppe = 1,2-bis(diphenylphosphino)ethane) and their parent trans-Ru-II(dppe)(2)(CN)(2) (1) were reported. Both the crystal structural data and MMCT (metal-to-metal charge transfer) indicate the existence of some electron delocalization along the Fe-III-NC-Ru-II arrays in complexes 2 and 3. The magnetic properties of complexes 2 and 3 reveal dominant antiferromagnetic coupling, and complex 3 exhibits spin-canted behavior below 6.5 K.
