Rational synthetic strategies towards complex coordination polymers and metal organic frameworks start with the design and synthesis of multitopic organic ligands. Use of organometallic ligands in the design and synthesis of MOFS is still at a very early stage.Recently we have synthesized a new organometallic ligand, 1-Ferrocenyl-3-(5-bromopyridyl)-prop-3-enol-1-one  (HL1),   and a new bimetallic  2D coordination polymer, {Cu[1-ferrocenyl-3-(5-bromopyridyl)prop-1,3-dionate]2}n [Cu(L1  )2]n polymer derived from it. Results from this study and the reports detailing the efficacy of poly-b-diketonates in crystal engineering prompted us to explore the synthesis and reactions of a new bimetallic ligand, in which two ferrocene moieties are connected to a pyridine ring through two b-diketoenol linkers. We will present results from our study describing the synthesis of a new organometallic ligand, 3,3'-(pyridine)-bis(1-ferrocenyl-prop-3-enol-1-one) (H2L3,5  )   , and   its reactions with different metal ions to form new polynuclear hetrobimetallic  triple stranded helicates.
