A special emphasis is devoted to initiating, developing and combining new physical properties within the heterometallic systems enclosing cores of three different spincarriers. The rational inclusion of 3d and/or 4f cations within the same molecular entity could generate new categories of heterotrimetallic complexes which possesses the special properties on photo magnets, luminescent or chiral compounds or with combined properties, namely magneto-luminescence or magneto-chirality. These new molecular materials open large perspectives to developing molecular "prototypes" for revolutionary optical, high-storage devices or in quantum computing. In this research the synthesis and characterization of Heterotrimetallic complexes of the type [RuCl(PPh 3)(L 2)](where L=bidentate Schiff base ligand of ferrocenylthiosemicarbazone) was attempted by reacting [RuCl(PPh 3) 3 ] with bidentate Schiff base ligand of ferrocenylthiosemicarbazide. During this synthesis the complexes obtained have been characterized by Elemental analysis, IR and Electronic spectroscopy. This confirms Heterotrimetallic Fe(II)-Ru(III)-Fe(II) complex with PPh 3. This complex finds its use as precursor for some carcinogenic drug and it paves the way to the area of superamolecular material research.

Developing a heterometallic system enclosing three different spin carriers has enunciated a wider interest in research as it possesses characteristic features for being photo magnets and with combined features like magnetoluminescence and magneto-chirality. These results in greater prospects in developing molecular "prototypes" for quantum computing and drug delivery. This study aims to synthesize the Heterotrimetallic complexes [RuCl(AsPh3)(L)2](where L=bidentate Schiff base ligand of Ferrocenyl thiosemicarbazone and Ferrocenyl-Nphenylthiosemicarbazone) and characterize them using physicochemical analysis and spectroscopic techniques. The results confirm that in the synthesized complexes, ligands are coordinated with Ruthenium atom via NS. Also, the biological studies ascertain its activity towards biomolecules as a potential antibacterial material and could also find its use as a precursor for some chemotherapeutic drugs and also in supramolecular material research.
