Water is the global solvent, being also an excellent solvent for stoichiometric and catalytic chemical synthesis. For this reason we are interested in the synthesis of organometallic complexes soluble in water. As a consequence of our research activity in this area we obtained the first example of a water-soluble air-stable heterometallic-polymeric complex {[(PTA)2CpRuDMSO]-�-AgCl2-}n [1] constituted by organometallic-metal-complex moieties. Some year later, we also presented the second example of an air stable hetero-poly-metallic polymer, the {[{(PTA)2CpRu-�-CN-RuCp(PTA)2}-�-Au(CN)4-]}n [2]. These new complexes display novel properties never found for organometallic complexes such as gel behavior in water. In the last years other research teams have presented new examples of polymers containing the ligand PTA [3] some of them with interesting properties such as catalytic and bactericide activity. We have extended the synthesis of this kind of backbone-organometallic-polymers to the new polymer complexes {[{(PTA)2CpRu-�-CN-RuCp(PTA)2}-�-MCl3-]}n(M= transition metals). Most of the new polymers are water-soluble and display catalytic, biological, optical and gel properties in water.
