Yx. Ma et al., SYNTHESIS AND CHARACTERIZATION OF CINNAMALDEHYDE FERROCENECARBONYLHYDRAZONE AND ITS COMPLEXES WITH LANTHANIDES, Revue Roumaine de Chimie, 38(5), 1993, pp. 567-572
A new ligand, cinnamaldehyde ferrocenecarbonylhydrazone, FeCONHN==CHCH
=CHPh(HL) (Fc=eta5C5H5FeC5H4) and its chelates with lanthanides, Ln(HL
)3Cl3 . 0-4 H2O (Ln = Y and lanthanides) have been synthesized by the
reaction of HL with LnCl3 and characterized by elemental analysis IR,
PMR, electrolytic conductivities, TG and DSC measurements. In these ch
elates the ligand coordinates to lanthanide ion in the keto form and t
he coordination numbers of the central ions are all equal to 8.
