Heteronuclear coordination polymers have attracted great interest with regard to their physical, electronic, catalytic and structural properties. However, the design and synthesis of heteronuclear coordination polymers constructed from multifunctional metalloligands is still at preliminary stage. We have recently communicated the synthesis of the 1-Ferrocenyl-3-(5-bromopyridyl)-prop-3-enol-1-one (HL 1) ligand and its heteronuclear 2D coordination polymer [Cu(L 1)2]n. Organometallic ligands of this type possess the  ferrocenyl and the functionalized pyridyl moieties, and the central  ketoenolate binding moiety. We have extended these studies to other halogeno-substituted derivatives, where the coordination behavior of the ligands will be compared. Also the impact of varying the position of the ketoenolate moiety on influencing peculiar coordination architectures and properties of resulting complexes will be discussed. Synthetic, spectroscopic and single-crystal X-ray structural studies of the ligands and the Cu(II) complexes will be presented.
