Syntheses, electrochemistry and crystal structure studies of novel cis-configuration biferrocene trinuclear complexes
摘要:
The syntheses and characterization of novel biferrocene trinuclear complexes for Schiff base ligand, S-methyl-N-(ferrocenyl-1-methyl-methylidene)dithiocarbazate thereafter abbreviate as HL), are described. X-ray diffraction studies established the structures of the palladium complex, PdL2 2 and the copper complex, CuL2 3. The geometry of Pd(II) in 2 is close to square planar and in novel cis-configuration with two ferrocene moieties in the same side, while that of Cu(II) in 3 is close to tetrahedral configuration. Electrochemical measurements suggest that the distorted square planar configuration of the Ni(II) and Pd(II) moieties, can effectively transmit the redox effects of the ferrocene moieties, while the distorted tetrahedral configuration of Cu(II) complex can not transmit the redox effects.
