Abstract
Reaction of 2-(2-aminoethyl)pyridine (L) with ferrocenecarboxaldehyde (FCAL) in toluene gives rise to LH, the 1: 1 Schiff base condensate of L and FCAL. Reduction of LH with NaBH 4 in methanol and subsequent protonation with stoichiometric proportion of hydrochloric acid enables to isolate the ferrocene bearing organometallic moiety, [LH 2 ]Cl.H 2 O. Replacement of the counter anion, chloride, by hexafluorophosphate in acetone afforded the target ferrocene appended organometallic precursor, [LH 2 ]PF 6 .H 2 O with satisfactory yield. [LH 2 ]PF 6 .H 2 O is characterized by C, H and N microanalyses, FT-IR, 1 H NMR and ESI-MS and cyclic voltammetry. The X-ray crystal structure of it has also been determined. The structure reveals that it is centrosymmetric (space group P2 1 /c).
