O(Cl)Fe(H2O) Iron(III) complexes [(C6H 5CH2OC6H4C=N-N=CHR)2], where R = H, 3; CH3, 4; CH3CH=CH, 5; C6H 5, 6; CH3OC6H4, 7; ClC 6H4, 8; C6H5CH=CH, 9 and C 6H5CH2OC6H4, 10 are formed when 4-benzyloxybenzoylhydrazine 1 and aldehydes (such as formaldehyde, acetaldehyde, crotonaldehyde, 4-methoxybenzaldehyde, 4-chlorobenzaldehyde, cinnamaldehyde and 4-benzyloxybenzaldehyde) react with iron(III) chloride. The complexation proceeds through the formation of intermediate carbohydrazone ligand 2, not the template condensation process. The carbohydrazone ligand coordinate to the metal via the deprotonation of enol form. The complexes have been characterized by elemental analyses, conductance and magnetic moment measurements, UV-visible, infrared and mass spectroscopic studies. The complexes are found to be paramagnetic but do not show any liquid crystalline behaviour, instead they decompose during melting stage.
