• centrosymmetric molecule

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 NaBH4 in methanol and subsequent protonation with stoichiometric proportion of hydrochloric acid enables to isolate the ferrocene bearing organometallic moiety, [LH2]Cl center dot H2O. Replacement of the counter anion, chloride, by hexafluorophosphate.in acetone afforded the target ferrocene appended organometallic precursor, [LH2]PF6 center dot H2O with satisfactory yield. [LH2]PF6 center dot H2O is characterized by C, H and N microanalyses, FT-IR, H-1 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).
