ABSTRACT:

Ferrocenyl-b-diketone ligands have been synthesised by the reaction of (ferrocenyl methyl) trimethyl ammonium iodide (FcCH2N+Me3I-), where Fc=C5H5FeC5H4– with sodium salt of -b-diketone [Na+CH-(COR1) (COR2), where R1= R2=CH3, R1= CH3, R2=Ph, R1= R2=CMe3]. The formula of the ligands (1-3) are FcCH2CH(COCH3)(COCH3), FcCH2CH(COCH3)(COPh) and FcCH2CH(COCMe3)2 respectively. The work also synthesised some complexes of Cu(II), Ni (II) and Zn(II) by the reaction of ferrocenyl methyl b-diketones with corresponding metal acetate in a mixture of water and dichloromethane (CH2Cl2). The formula of the complexes are [Zn{FcCH2CH(COCH3)2}2], [Cu{FcCH2CH(COCH3)}2], [Ni{FcCH2CH(COCH3)(COPh)}2] and [Cu{FcCH2CH(COCH3)(COPh)}2] . The ligands and complexes have been characterizied on the basis of infrared spectra, UV-visible spectroscopic studies, Elemental analysis, Magnetic moment, Conductance measurement, Metal estimation, Melting point, NMR spectra and other physical properties.
