Several new complexes of some transition metal ions with organometallic compounds were derived from ferrocencecarboxylaldehyde and 4-amino-2-hydroxy pyridine. These organometallic complexes were investigated by using some analytical techniques like infrared, mass spectra, electronic spectra, electron spin resonance, thermal analysis, magnetic moment, conductivity and antimicrobial activity. From the obtained elemental analysis data, organometallic compounds complexes shows 1:2 [M: L] ratio and general formula of the complex is [ML 2 .2H 2 O]. These complexes revealed a non-electrolytic nature. The magnetic moment values of the complexes exhibited the paramagnetic as well as diamagnetic in nature. The coordination behavior of the metal ions towards to the investigated organometallic compounds takes place through >C=N-and-OH groups. The electronic spectral data shows that all the complexes are covalent in nature, octahedral structure with coordination number six. Organometallic compound complexes were loses two water molecules subjected to simultaneous thermo gravimetric analysis, to study their decomposition mechanism and thermal stability. Mass spectra of the organometallic compound and their complexes are matched with theoretical values of the masses. The prepared organometallic compounds and their metal complexes were screened for their antibacterial activity against some bacterial species, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus Pyogones. The Antimicrobial activity data show the metal complexes to be more active than the parent organometallic compounds.

The synthesis, characterisation, spectral studies, antibacterial and fugal studies of some transition metal ions like Mn ++ , Co ++ , Ni ++ , Cu ++ , Pd ++ and Pt ++ complexes of ferrocene based Organometallic compounds have been reported. The coordinate bonding of nitrogen to the central metal atom which reduces the electron density in the both azomethine link and thus lower the-HC=Nabsorption. The elemental analysis data exhibit the formation of 1:1 [M: L] ratio with coordination number six in the all complexes. The complexes have with octahedral geometry and D 4 h symmetry. The ferrocene based organometallic compound shows a molecular ion peak at m/z 482.4 which is equal to theoretical molecular weight. The molar conductance value indicates that, they are non-electrolytic in nature. These complexes were tested with some bacteria and fungi.
