“…[9,10] The coordination of the [Au(CN) 4 ] À unit to the nitrogen atom N3 in pta does not significantly affect the structural features of the cage in comparison with other Ru(pta) complexes. [25,29] It is interesting to note that all attempts to obtain polymers from the monomer 1 led to 3 but not to the expected [{Cp(pta) 2 Ru(CN-kC)}{Au(CN) 4 À anion by the nitrogen atoms of one layer and the N1 and N6 atoms of the pta units in two different adjacent layers (Figure 3). The shortest hydrogen contacts between atoms in contiguous layers were found to be 2.723(2) (O1-O2), 2.815(3) (O1-N6), 2.839(3) (O1-N1) and 2.944(4) (O2-N2C), which are longer than a hydrogen bond but shorter than the sum of their van der Waals radii.…”

Selection of the combination of metal, ligand set, and spacer groups that are most appropriate to form a coordination complex with a desired function are of paramount importance in supramolecular chemistry. In particular, the establishment of reproducible methods to accomplish controlled selforganization of molecules to form polymers and homo-or heterometallic coordination aggregates is an important field of research.[1] Although important advances have already been made, few metallopolymers, which are one of the most exciting classes of functional materials, are water soluble. An important example of a water-soluble polymer is the polyferrocenylsilane-b-polyaminomethacrylate copolymer described by Manners and co-workers, [2] as part of their ongoing study on metallocene-based polymers.[3] Recent examples also include the water-soluble metallopolymer obtained by reaction of bipyridyl-appended poly(p-phenyleneethynylene) (PPEs) with metal ions in organic and aqueous solution. [4] Other examples of ligands that afford coordination polymers with various topologies and applications are ferrocenyl groups bearing bipyridine (bpy) [5] or carboxylate moieties.[6]A recent example of a non-water-soluble multimetallic polymer is [Sm(, in which the CN ligands bridge the samarium and ruthenium metal centers.[7]The first air-stable water-soluble multimetallic polymer that includes mixed P,N ligands as metal-coordinating spacers has been recently reported by us.[8] This heterobimetallic complex is based on two metal-containing moieties, [CpRu]À , and is bridged by the cagelike water-soluble monodentate phosphine 1,3,5-triaza-7-phosphaadamantane (pta) in an unprecedented P,N coordination mode. More recently, the synthesis of silver coordination polymers containing pta bridging molecules in a tridentate P,N,N' coordination mode [9] has been reported and several examples of pta N coordination have been presented.[10] Therefore the pta molecule could be an excellent ligand from which to obtain water-soluble Ru-Au polymers which could have interesting and useful properties for a variety of applications such as magnetism, [11] nonlinear optics, [12] electrocatalysis, [13] photocatalysis, [14] photovoltaic, [15] template formation of ordered networks, [16] advanced electrode materials, [17] and conjugated coordination polymers.[18]Herein, we describe the first water-soluble, air-stable heterobimetallic polymeric structure based on two metalcontaining moieties [CpRuCNRuCp] + and [Au(CN) 4 ] À , bridged by pta in the P,N coordination mode. Interestingly, this complex display gel-like properties [19] in water, specifically a thermally controlled volume transition. To the best of our knowledge, this is the first example of an coordination polymer network that is sensitive to its environment.

“…The coordination geometry around the ruthenium atoms is more regular, with the Ru-Cp (centroid) distance (1.868 ) slightly larger than that found for [CpRuCl(pta) 2 ] (1.846 ), [27] while the Ru-P separation (average: 2.2618 (8) ) is consistent with that found in the few other Ru-pta derivatives that have been studied by X-ray diffraction. [22,25] This is the second known compound in which the pta acts as a bidentate ligand, [8] bonded in this case to a ruthenium with the conventional lone pair of electrons of the phosphorus atom and to the gold atom of the tetracyanogold-(III) moiety by one of the three nitrogen atoms (N3) contained in the adamantane cage ( Figure 2). …”

[6] A recent example of a non-water-soluble multimetallic polymer is [Sm(H 2 O) 5 ][Ru 2 (bpy) 2 (CN) 7 ], in which the CN ligands bridge the samarium and ruthenium metal centers. [7] The first air-stable water-soluble multimetallic polymer that includes mixed P,N ligands as metal-coordinating spacers has been recently reported by us. [8] This heterobimetallic complex is based on two metal-containing moieties, [CpRu] + (Cp = cyclopentadienyl) and [AgCl 2 ] À , and is bridged by the cagelike water-soluble monodentate phosphine 1,3,5-triaza-7phosphaadamantane (pta) in an unprecedented P,N coordination mode. More recently, the synthesis of silver coordination polymers containing pta bridging molecules in a tridentate P,N,N' coordination mode [9] has been reported and several examples of pta N coordination have been pre-sented.
